EMPIRE ELECTRON AMPLIFIERS

Logo-- EMPIRE ELECTRON AMPLIFIERS--

My name is Steve White. I am a vacuum tube amplifier scratch builder from Peterborough Ontario Canada.

I also go by the name

EMPIRE ELECTRON AMPLIFIERS

and

E E AMPS.  

I am a one man operation building the entire amplifier myself by hand. I learned this old world art form from a well known and admired builder from California by the name of Lance Cochrane.

As his apprentice, I worked very hard to develop and perfect my own style and master the electronic theories. In order to accommodate the various differences and characteristics of the different components I use (such as different tubes and transformers etc.), I must make changes in the circuit to achieve the best results in sound quality.

This tuning is the make or break point in the successful completion of any amplifier. This can only be accomplished by listening and making the appropriate changes using your ears. Your ears will tell you if it sounds good or not, not any kind of measuring equipment. Those devices are simply not accurate enough. With that said, I have measured the T.H.D. (total harmonic distortion) on these units and they consistently read .001  T.H.D., so if you like numbers, there you go.  

Understand that it is more important for an amplifier to sound good, take you there, be engaging, and make you enjoy the music, and that cannot be calculated or measured using math.  Numbers and formulae will only get you to the dart board, somewhere on that dart board, but tuning with your ears gets you to the target every time!  After all, the end user is your ears.

Handcrafting these amplifiers has been my calling and passion for quite sometime now and I am more than happy to share my work with all of you out there who are like me, passionate about great uncoloured sound reproduction.

What I build are 100% handcrafted, one-of-a-kind, custom, never to be duplicated, signed and dated on the inside ~ as all great works of art should be, vacuum tube amplifiers.

I build all three types of vacuum tube amplifiers, power, integrated and phono stage pre amplifiers.

I will bet that once you’ve heard one of these amplifiers, you will say that it is the BEST sounding amplifier you’ve ever heard, and once you’ve seen one of these amplifiers, you’ll say it’s the most unique translation concept of electronics you’ve ever seen!

About this blog;

This blog is a work in progress and has been constantly built upon since 2008.  Here you will see nearly every vacuum tube amplifier I have ever made.    For the most part, the amplifiers appear in the order they were created.  There is a lot of technical information about the amps in the write-ups, therefore any question you may have about the circuits uses or the construction of the amps is answered somewhere throughout this blog.  To keep the blog a fun and informative read, I try not to be too repetitive about certain aspects about the amplifiers, so just to aid you on the most asked questions, I’ll try to answer those ones here:

1- Yes, my amps are all auto-biased, and never need adjusting ever.

2-Yes, all push-pull amplifiers are auto balanced and never need adjusting ever.

3-I do use all new, high-grade parts for the builds except the transformers which are vintage.

4-Yes, I do build and tune the entire amplifier by hand myself.

5-My chassis are made of mild steel usually 18 gauge and made to order according to my specifications by a local metal fabricator.

6-All my amps (with the exception of a few) are professionally painted in a proper paint facility using the best paints available (usually Marine grade).

7-I can build single ended, push-pull, and push-pull-parallel power and integrated vacuum tube amplifiers.

8-I can also build my own version of a phono stage preamplifier as well as a line stage pre amplifier.

9-Phono stage pre amplifiers are ONLY available to customers who already own one of my power or integrated amplifiers.

10- As I build custom amplifiers, I can build anything you or I can dream up.  That’s what makes it fun!

11-No matter the design, tube compliment or power rating, all my amps sound equally as good as the other with minor personality differences from major components such as transformers.  A tuning process is performed with every amplifier, resulting in uncoloured tonal perfection.  Therefore, every amplifier has its own personality, but the overall sound quality, staging, presence, and balanced tone is a signature that is identifiable to my work.

12-Tuning is method of which you remove all component tolerances and voltage differences so that the end result equates to a predetermined value together with your ears.  Not much different than tuning a piano or guitar.


Our local news Paper “The Peterborough Examiner” published an article about me and my work back in January 2009. Here is a copy of that….

807 P/P Ultra-linear Power amp

Here we have an ultra-linear push pull 40 watt per channel 807 power tube amp using 807 radio transmission tubes.  This was the fourth amp I ever made, and was my very first sale.  It is also the only Ultra Linear amp I’ve ever made.   The owner would never part with it saying he’s never heard another amp sound as good as this one.  I won’t divulge what he paid for it, but I will say he was very wise to buy it when he did.  Those who bought back in the early days now own an investment, as these early amps fetch nearly triple the original sticker price.  This is definitely the case here.  Sold.

Electric Purple 807/5933 Ultra-Linear (40 watts per channel)

 
Ocean Blue 807    807  P/P Power amp

The amplifier I have for sale here is the Ocean Blue 807.  This is a power amplifier using four 807 radio transmission tubes, three 6SN7GTB input tubes, and a 5V4 rectifier tube.  Very similar in design to the Electric Purple UL unit above, but this one runs in Tetrode mode.  

It’s putting out a modest 30 watts per channel. Built on a 12″ x 12″ x 3″, 18 gauge steel chassis, handcrafted to my specific specifications.  This is a stunning Tube amplifier painted a beautiful cobalt blue with tons of ice pearl metal flake in the 3rd of 8 coats of clear.  Put this amp under a 50 watt quartz lamp and watch it sparkle!   The design, inspired by those old black and white Frankenstein movies from the last century, has taken vacuum tube amplifier design to a whole new level.  I like to design works of art, as well as great amplifiers.  I wanted to show the audio world that an amplifier doesn’t have to be black, or brushed aluminum,… how boring!  

A tube amp should capture your mind and imagination and make you take a look!  My amps do that!  They should also make you stand up and listen.  Mine do that too!  They really do sound every bit as good as they look.  Owning one of my amps, like this one, means you are the ONLY one in the world with an amp like this, made by me.

This is a push-pull 807 tetrode power amplifier softly running the plates of the 807 radio transmission tubes at a very conservative 330vdc.  These RCA 807′s will last years at these voltages.

Priced at $3,275.00    Sold.

 

After looking six years for a new amplifier, a new client of mine chose this amp to be his old unit’s replacement.  Yes, all the way from Alberta he purchased this Empire Electron Amplifiers 807 power amplifier without actually hearing it.  Going purely on what he knew about me and my work.  Now that says something about my reputation, doesn’t it!  So, after several questions and comments, my new client committed to his new amp without any hesitation.  I am truly humbled by this experience!

About the 807 tube…

I’d like to talk a bit about the 807 radio transmission tube for a minute. The 807 was originally released in 1936 as a variant of the 6L6.  Having the plate terminal connection at the top of the tube meant that it was far away from the base and the other connections, and therefore could be designed to operate at much higher voltages with no fear of those high plate voltages arching over to one of the other pins on the base.  This made the 807 perfect as a transmission tube.  It is important to note that the 807 is not electrically identical to the 6L6 and therefore has its own operating parameters and purposes.      The 807 later became widely used during World War II in radio transmitters for the army, taking its production numbers to the stratosphere. Used as the final output tube, it’s a very robust and powerful tube capable of 750 vdc on it’s plate or anode. The operator of the field radio was called a ‘Sparky’ due to the fact that he was often jolted with the high voltages used in the radio as he operated and maintained the unit.  Most 807 tubes are military tubes and therefore are superbly built able to withstand just about any environment. These operators were highly skilled and a tight bunch that used to hang out together and share thoughts and ideas. When they would say, “I’ll meet you for an 807 later on.” they meant a cold beer. The 807 tube having that Coke bottle shape to it was the reason for the reference.

The 807 was therefore never intended to be used as an amplifier tube in audio Hi-Fi, but I really liked the shape and having the plate terminal on the top similar to a spark-plug,  gave me the option of some really new and unique design possibilities.   I made adjustments and designed my circuit around the 807 to accept the unique voltage and operating parameters of the tube. Success meant that I would have an amplifier available to my clients that no one else could offer. So beautiful and unique, the 807 amplifier sounds as good or better than any other amplifier I’ve ever heard.  As far as I know, the 807 amplifier is an exclusive offering that only I manufacture as I have not seen anyone else use this tube other than Ham radio operators.  All of my 807 amps run at voltages far below the maximum allowable so expect the tubes to last many many years, and since the 807 is so plentiful at very reasonable prices, mainly because the only ones using the 807 are the Ham guys that have tubes based equipment, makes the 807 amp a bargain to re-tube.

Here’s an up close picture of an RCA- 807 Radiotron tube…

6L6 P/P Integrated amp

If you grew up as a teen in the 1980s as I did, then you remember the Ford Mustang GT as being the best bang for the buck!  

For $16,500 you could buy a Mustang pretty much fully loaded with the GT package that included the potent 5.0L, 302 cubic inch 225 horse power engine.  That car with the V8 could take on anything up to $100 grand including exotic cars like the Chevrolet Corvette worth then $40 grand,  a Buick Regal Grand National costing $35,000  and many of the very exotic German and Italian beauties costing over $100,000.  
I remember those days and had one of those Ford Mustang GTs.  It always put a smile on my face every time I drove it.  Today I drive a nice little BMW 3 series that I love just as much.  A 330ci to be exact.  Back then it was all I could do to scrounge up $10,500 to buy a two year old car.  
I thought a lot about my Mustang and decided to try and incorporate Ford’s idea of putting decent power in a lesser expensive package with all the same performance and great looks of the more pricey units.   Just do a few things differently to make an amp less expensive,… so I did.  I went all out and built this very potent 6L6 / EL-34 / Kt-77 integrated power house.  I assure you that this newest integrated has all the muscle and performance that any of my other units costing $4,000.00 or more do, and to top it off, it’s integrated!  That single upgrade alone, normally costs $400!  So what is the price of this new amp you ask?  Well, let me tell you about it first.  
This is a 6L6 / EL-34 / Kt-77 integrated amp conservatively rated at 30 watts per channel using dual 6CA4 rectifiers, a pair of 6C4 pre amp input tubes, a pair of 6CG7 inverters, and a quad of the power tubes I’ve already mentioned.  Pictured here is a quad of Russian 6L6GCs.  The unit measures 15″ x 8″ x 2″   The colour is Empire Slate Grey to match the volume control knob located in the centre of the mirror, making this a very handsome unit indeed.  On the back panel you’ll see the push-in speaker binding posts next to the RCA inputs followed by the IEC and last a 3a fuse.  
This is a very compact unit, but don’t let its smaller size fool you!  I played this unit head to head with my 100 watt per channel EL-34 mono blocks, and this power house kept right up with them until it became too loud for me to take with no, that’s ZERO deterioration in sound quality.  This integrated is a sleeper!  I was quite surprised myself to be honest.  Come test drive it for yourself.  I’d be glad to show it off!  Oh yeah, the price?  It’s $2,500.00   That’s far below the usual price of a 6L6 integrated.  It’s actually close to a grand less!   That’s a 25% savings with zero compromises.
 
Just like the Ford Mustang GT of 1986, this is the best bang for the buck!  I’ve only got one, and I only plan to make one, so here it is… 
Available.

6AQ5 P/P Power amp

This army green 6AQ5 runs in Tetrode mode at 15 watts per channel with 12AU7 input driver tubes.   The owner would never part with it.  If this amp were for sale today, it would be priced at $1,800.00  Since this was my second sale back in 2008, it remains a solid investment,  as the customer bought when my work was not known.  Sold.

Army Green 6AQ5 (15 watts per channel)

The Afrikaan Eclipse Orange 807 P/P Triode / Tetrode Power amp

Now, here I have a very unique 807 amp that can run in either Tetrode or Triode mode via a switch on the back of the amp that can be selected on-the-fly while the amp is in operation with absolutely no danger to the amp. Most amps must be powered down when any mode selecting is taking place but not my amps. You can select at anytime.

This amp will give you 40 watts per channel in Tetrode mode and about 30 watts per channel in Triode mode.

It also uses a solid state rectifier so a stand-by switch is used to allow the tubes to be warmed up first before adding the 359 vdc to the plates of the 807 radio transmission tubes.

As with all of my amps, this is a unique design of my own, never to be duplicated.

This amp is no longer available.  It went to all time favourite teacher from high school Mr. Grant Soper as a gift.  It’s really nice when things in life come full circle!

Not Available.

Afrikann Eclipse Orange 807/5933 (40 watts per channel) )(available $3,800.00)

The 807 Bookshelf amplifier.  807 P/P Power amp

The amplifier I have for sale here is one of my favourite styles and layouts. This one has inspired quite a few of my later creations. The 807 ‘Book-shelf’ amp.  

This is a power amplifier using four 807 radio transmission tubes and three 6SN7GTB input tubes, putting out a modest 40 watts per channel. Meant to be long and lean to sit on a shelf that has a white wall behind it. You see, there are six blue neon lights that line the back panel of the amp and with the aid of the white wall behind the amp, you will see a blue glow along the back of the amp.

To help with this effect, I had the amp painted white and added blue pearl metal flake imbedded in the eight coats of clear on top of the white paint. This makes the entire amp seem to have a blue glow as it picks up the blue light that is being reflected off the back wall. The look and effect is really spectacular! Operating with a set of 6 amp silicon diodes for AC/DC rectification, this amp uses the dual set of On/Off and Stand-By switches to allow for tube warm up time during start up.

A timeless, classic 1950′s throw-back, with balance, asymmetry, and simplicity like no other amp I’ve created.  Truly a testament to my designs and functionality.

Priced at $3,800.00  Available.

Number 1        6L6 P/P Power amp

The very first amplifier I ever made,  a beautiful Sunscape yellow 6L6 / EL-34 with 40 watts per channel.  I said I would never part with my first amp, but when a collector offered me an offer I couldn’t refuse, I didn’t.  This customer is the classic audiophile and one who loves my work.  He has four of my amps.  One of each type including the red V push-pull-parallel 100 watt per channel unit I made custom for him.   I have a number of clients who own multiple amplifiers.  It really does become an addiction!  Sold.

Sun Scape Yellow 6L6 (40 watts per channel)

The Twins  6L6 P/P Power amps

Dubbed the ‘Twins” even though they’re not, each of these 6L6 / EL-34′s put out 40 watts per channel in a Tetrode mode.  One is in Peterborough and the other in California.  Both have had these units for some time now, and are avid audiophiles.  I guess they are twins in one aspect, they both sound identical.  Both Sold.

6L6  P/P Power amp

This amp resides in Toronto where it’s owner who has owned units worth $20k plus bought this amp from me. He has since sold off ALL of his current and vintage tube and solid state amplifiers. In his own words Mike says my amplifiers ‘eat’ everything out there! Even the most expensive gear can’t compare, he says. This is a sentiment I hear all the time, just take a look down at the bottom of the page where you’ll be able to read comments left by my customers. They speak volumes!

Single Ended 6AQ5  Power amp

This little 6AQ5 single ended amp putting out 6 watts per channel would surprise you. The owner of this amp has four of my units including the 1950′s red push-pull-parallel 100 watt per channel monster I made just for him.  With 300 vdc on the plates of the 6AQ5 power tubes, this amp can easily put a solid state amp pumping out 10 times the power to shame!  Sold.

Hammertone Slate SE- 6AQ5 (5 watts per channel)

6L6 P/P Power amp

This EL-34 / 6L6 amp styled in a 1950′s theme lives here in Peterborough. Just an other example of how word of mouth promoting my work has really spread here in town. I have 14 clients in town who own one or more of my units. All through word of mouth or being at a client’s home and seeing/hearing one of my amps and you know how it goes the next thing you know, they are calling to place an order.  Sold    EL-34 / 6L6  40 watts per channel

Single Ended 807  Power amp

This has to be my favourite single ended amp. The design was taken directly from the Afrikann Eclipse orange 807 that does Tetrode and Triode modes. Bought by a gentleman who makes very nice and expensive custom speakers, loved this unit the second he heard it. The speakers he makes are very efficient so he didn’t need more than 20 watts per channel. This amp delivers 25 watts per channel so it was a nice fit with plenty of head room thanks to the large envelope of the 807 radio transmission tubes. With 409 vdc on the plates, the only way to really describe this amp is magic! The amp can also run 5933 power tubes. They are an even higher grade of military 807.   Sold.

New Blue Single Ended 807/5933 ( 20 watts per channel )

6L6 / 12AU7  P/P Power amp

Owned by a client who was a friend before I started building amplifiers, was a driving force for me where audio was concerned– Professor Driscoll of Trent University owns this amp. Jim has the pleasure and privilege of being my second set of ears. When ever I complete a new amp, I let Jim take it for a test drive. He has always loved my work, and he really enjoys the job!

His amp is a 6L6 / EL-34 with 12AU7 driver tubes and a 5U4G rectifier putting out a conservative 35 watts per channel.  Sold.

Old Console Radio style 6L6/5881 ( 35 watts per channel )

Big Purple  6L6  P/P/P  Power amp

I have been getting a lot of requests for one of these ~ here’s the new 80 watt per channel Push-Pull-Parallel 6L6. Huge sound stage and great depth. Way more power than anyone really needs!

With a pair of toggles in front of that massive power transformer that act as pre-heat and stand-by, and on either side of them is a red jewel neon pilot lamp.  Such a nice, clean look!  The power transformer is a Baldwin and the outputs are Harman Kardon.

The amp can be ran with a number of different power tubes such as 6L6GC, Kt-77, 7581, or EL-34 with no need for any kind of adjustments ever.  The auto bias and auto balance components make all adjustments for you.  All my amps work that way.  Keeps things simple and fun!

For those of you who have been following my work and this particular amplifier, here it is all finished! Painted a stunning electric purple. The tuning is all complete and it sounds fantastic! Your neighbours will be calling the boys in blue if you crank up the volume on this one!

Sold long ago to a great guy would just had to have the big purple amp.  I’ve got to do a few more in purple.  What a great colour!

Priced at $5,000.00   Sold.

Spectacular depth in this paint work.  8 coats of clear.

Single Ended 6L6 Power amp

This next amp is a single ended 5881. The chassis measures 10″x 6″x 2″, perfect for a condo where room is at a premium, or in the study. Depending on what rectifier tube you choose, you can run 6v6, 6L6, 5881, or EL-34 power tubes. A very fun and versatile little amp!  Sold.

SE-5881  20 watts per channel

6L6 P/P/P Power amp

Since the last push-pull-parallel was so successful, I’ve been commissioned to build another one.  Since this amp was being designed for a real techie, I wanted him to be able to have fun trying different output tubes. With this amp, he can run 6V6, 5881, 6L6, Kt-66, Kt-77, and EL-34 simply by changing rectifier tubes and with the addition of a switch, he can turn off one of the two rectifier tubes to give him the option to change the operating voltages from 290vdc all the way up to 380vdc.

Designed to have a 1950′s flair, here is my next Push-pull-parallel amplifier.   Sold.

PPP-almost any tube, from 40 to 100 watts per channel

Caterpillar  Amp  6L6 P/P Power amp

Here’s the next available amp. Designed for the heavy machinery crowd, the CATERPILLAR amp. With a heavy-duty On/Off switch and classic amber jewel pilot light, and 4-8-16 ohm selector switch on the back panel, this amp painted the classic Caterpillar yellow with brilliant white pearl metal flake imbedded in the eight coats of clear gives the guy who has everything, even more.

For those of you who know the Kt-66 / 7581 tube, this amp was designed to take that tube.   By using a 5Y3 rectifier, you can run 6V6s also.  This is priced far below the other 807′s or Kt-88 but is by no means lacking in power, sound quality or looks. The reason being, 807′s are much more involved to build, and a Kt-88 requires transformers that are both rare and expensive.

At the time when I built this amp I had a good supply of vintage cloth wire, so the entire circuit here was wired using it.  Yes, all point to point wired using traditional cloth insulated wire.  Something no longer done.

Priced at $2,800.00   Available.

The Firecracker Amp   6550 Power amp

Now, here is an amp that a lot people wait in the weeds for; a 6550 / Kt-88 / Kt-66 / El-34 push-pull power house!  This is the Firecracker amp.  Named as such because of the strikingly bold red paint with lots of ice pearl metal flake in it.  Power is 70 watts per channel in tetrode mode.  

Strictly an 8 ohm unit, as the Canadian Electrohome output transformers only had 8 ohm taps. The power transformer is also Canadian, made by the Hammond transformer company.  These are very heavy and capable transformers, and the power transformer is somewhat rare, as it’s high voltage taps and size are capable of handling the current demands of 6550.  With power to spare, it’s been built on a sleek 2″ chassis with a footprint of 20″ x 7″.  

A beautiful emerald green jewel light indicates power with the switch on the side as I like to do it.  Gold plated RCA input jacks on the back, along with a set of 5 way binding posts for your speakers.  This is a power amp, so therefore a pre amplifier is needed.  If you choose, you can run any of my power amps directly with an I-Pod with no need for a pre amplifier.  As with all of my amps, the circuit is all point-to-point wired, and in this case, I used NOS vintage cloth wire to build the circuit.

I don’t make too many amps like this, not because I don’t want to, but because it’s very hard to find a power transformer with these voltage and current parameters.  In fact, this is only one of two 6550 / Kt-88 amps I’ve made to date.  Big, Bold, Powerful sound in a small package.  One of my favourites for sure!

Priced at $3,800.00  Available.

Flash-Quattro        807  P/P Power amp

Amplifier number 29 is named ‘FLASH-QUATTRO’ or four flashes. The name came to me while building this new 807. I was thinking of how art-deco the 807 tube really is and the old 1930′s series called Flash-Gordon came to mind. The name seemed to fit, and since there are four 807 tubes the Italian word ‘quattro’ meaning 4 just seemed to have the sound and feel I was looking for, hence the name.

This new 807 is rated at 40 watts per channel and is painted with the exact same colour and affect as the Fire-Cracker amp. This colour is called ‘fire-cracker-red’ and the affect is ‘ice-pearl’ metal flake. The colour and look seemed to really suite this amp as well.

Flash-Quattro has very unique output transformers, in that they have output taps for 1,4,8,16 ohm speakers. I’ve added a selector switch on the back so that the user can choose which impedance he prefers on-the-fly. No one does this, but to me it just makes sense to do things this way.

You can now visit Flash Quattro in Port Hope Ontario on the old down town main street at a restaurant called ‘Black Beans’. The owners had spent a considerable amount of money on their sound system there and wanted one of my works to be the heart of it. If you’re ever in Port Hope Ontario, drop into Black Beans for a fantastic dinner and hear some really great music amplified through one of my creations.

6L6 Rebuilds    6L6 P/P Power amps

I recently had the opportunity to re-build a pair of stereo organ amps that would be used for Hi-Fi. The customer initially brought them over to my house in their original form with the original 6BQ5 circuit to see if they sounded as good as my amps.

Within 5 seconds it was clear that these units deserved to be reconstructed keeping only the chassis and transformers, the rest of the circuit would be stripped out, as they did not sound good at all. I suggest to the customer that I could be-build these units into really great sounding 6L6 monsters instead of 6BQ5 units. After answering a few questions, he agreed to the re- construction.

Here is the result….

That’s how it goes with my amps, once someone hears them on his own stereo system, and the amp being the only thing that is changing, they have to have it.  The sound improvement over what they already have is unmistakable!   They can never go back to what they were used to listening to ever again.

6BQ5 P/P Power amp

One of my transformer suppliers sent me 2 of these mono Baldwin Organ chassis. I liked the tube layout, so I turned them into 2 stereo 6BQ5 push pull 12 watt per channel amps and painted them both black. The only visible difference between the two is one has a pilot light where the other has a tube. They each have different output transformers but the power transformer is the same on both. One went to the transformer supplier- Steve, as his personal amp, and the other went to Tim at Bluestreak Records who has been a huge promoter of my work.

The Titan     6L6 P/P/P Integrated amp

The best way to describe this next amplifier is it’s a Titan. It has to be the biggest, badest, heaviest and most powerful amplifier I’ve made to date! Weighing in at just under 60 lbs. this push-pull-parallel EL-34 / 6L6 is conservatively rated at 110 watts per channel using EL-34 tubes. Capable of driving 8 or 16 ohm speakers via a switch on the back panel. This amp is a tube roller’s dream. Simply by plugging in which rectifier tubes you want to use, be it a pair of 5Y3′s, 5R4′s, 5U4′s or even 5AR4′s you can match the correct plate voltage with what ever power tubes you choose, be it a set of 6V6′s, 6L6′s, 5881′s Kt-66′s, Kt-77′s, EL-34′s, or even 7591′s.

You also have the choice of running the amp in push-pull instead of push-pull-parallel simply by not installing the front four power tubes and switching off one of the two rectifier tubes via a switch located on the right hand side of the chassis. The signal and phase-inverter pre amp tubes used are my favourite large dual triodes 6SN7′s.

Now, about the transformers, seeing that this amplifier has to drive thirteen tubes, I thought it only made sense to use a separate filament power transformer. The transformer right next to the larger power transformer is the 20 amp filament transformer. By doing this, I’ve removed the heater load off of the main power transformer which now only has to supply the high voltages the amp needs. By sharing the load this way, the main power transformer will not be taxed nearly as much. The output transformers are massive Hammonds that can easily handle the wattage this amp delivers.

You will notice a volume control knob located right smack in the middle of the mirror in front of the amp that’s surrounded in pure copper foil, and that is because this is a fully integrated power amp with a line stage pre amplifier built into it. That means you do not need to buy a separate pre amplifier. You only need to plug in your CD player, satellite, MP3, I-pod, or what ever type of line stage device you like to use, directly into the amplifier. There are two benefits to an integrated amp, one, you don’t have to go out and spend money on a separate pre amp, and two, you are amplifying completely with tubes throughout the whole amplifying process from pre amp to power amp, and that makes it sound better, way better!

Priced at $5,800.00 this Titan will drive what ever speakers you have, and well! If you want an amp that has huge power, great depth, and sound stage that takes you to the concert, this is the amp!

It was sold to a guy who wants everyone on his lake to know that he has this powerhouse! Another amplifier of mine living here in Peterborough on Chemong lake. I wouldn’t want to be his neighbour, but then again, I wouldn’t want to be mine either! The Peterborough / Lakefield police will be busy with noise complaints this summer.

The Mini Titan      6L6 P/P Integrated amp

Here is the little brother to the PPP-6L6 / EL-34. This integrated amp that is a 30 watt per channel push-pull 6L6 / EL-34 .  Went to a client who owns four of my units.  Again, this unit went one of my customers who own multiple units of mine.  Like is said, it’s an addiction.

Black Beauty       6L6 P/P Power amp

Everybody likes black, don’t they? Black definitely has it’s place, and here is a great example of that!

This is a great looking 6L6 / EL-34 power amplifier built for two very good friends of mine.  They have this unit as a focal point in their living room. With 15 foot ceilings, nice hardwood floors and 500 square feet of space in this room, this amplifier sounds as big as the entire house!

Using a trio set of vintage Baldwin transformers that are total overkill and running at 357 VDC on the plates using 6L6GC power tubes. A trio set of 6SN7GTB’s and a 5U4G rectifier complete the tube line up. This amp is rated at a conservative 40 watts per channel. Use a 5AR4 rectifier and get close to 50 watts per channel with no trouble at all.

With a 22″ chassis, the 6L6GC’s are afforded great radiant cooling due to being spaced 5″ apart from each other. This is a text book design, with great cooling, great symmetry, and a very appealing look. One of my favourites!  Sold.

V-2        1625 Single Ended Power amp

Next is a very unusual design I came up with one morning as I mulled over new design ideas. I thought, there are a lot of car and motorcycle guys out there, so what can I make to appeal to them? And then it hit me, make an amp to look like an engine! Since I used to own motorcycles all of which were the wrist rocket type, and my favourite by far being my Ducati 748. I thought about making an amp that looked like a V-Twin. Sure, a single ended amp that looks like a 90º V-Twin. So here it is…

It really ended up looking like something you’d find in a Hydro-electric sub station or a 1930′s Art Deco movie set.  Looks powerful, and it is!  Looks deadly, but it’s not.

20 glorious watts per channel with 375 volts on each of those anode wires using 1625 radio transmission tubes and a pair of 12AU7 signal tubes. 1625′s are electrically the same as 807 radio transmission tubes, except they have 12 volt heaters and use large 7 pin sockets. 807′s are 6 volt and use 5 pin sockets.  Sold.

6BQ5 Single Ended Power amp

Here is a very small but great sounding Single Ended 6BQ5 power amplifier. Perfect for the study or small space where you want reasonable volume levels.  Sold to a repeat customer.

Pumping Iron         Mono Blocks  EL-34 P/P/P Power amps

The deciding factor of what I build next is almost always dictated by what transformers I have at the time. When opportunity presents itself, and it often does, I just go with it. This is the case with these next two mono-block amps. Do you like to pump iron like I do? Well have a look at these massive Hammond power transformers! I have never,.. ever, seen such huge and capable power transformers!

Just ONE mono-block weighs OVER 50 lbs.

These are a once in life time offering, as I will likely never ever see these transformers again. Believe it or not, they were powering only TWO 6L6GC’s in their original form. Now they are push-pull-parallel 100 watt each, monster mono EL-34 / KT-77 power amplifiers. These could power a dance club and never break a sweat!

They each have an IEC power-cord connector, Cardas RCA and speaker binding posts for those of you who appreciate, and want very high-end connectors. There is also an un-switched A/C outlet on the top of each amp with it’s own separate 5a fuse to plug in what ever other Hi-Fi gear you may have, and therefore you can take advantage of only needing to buy one nice power-cord.

A rotary Ω selector to select between 4-8-16 ohms to match up with what ever speakers or speaker arrangement you have, meaning, these units are powerful enough to run say two 8Ω speakers in series which would give you 16Ω or you can run the same two sets of 8Ω speakers in parallel to give you 4Ω.  Configuring this way allows you to have multiple speakers running off of one amplifier.

The only requirement is wattage and enough wattage to run multiple speakers in such arrangements which these amps have plenty of.  The combinations are endless.

Painted a beautiful Hammertone Jet-Black with ultra fine ice-metal flake, these twins are fine examples of great industrial art!

Priced at $5,800.00 for the pair.  Available.

Mirror Images     EL-34 Mono Blocks P/P/P Power amps

Now, while I’m on the subject of Mono-blocks, here is another beautiful pair. These, made with potted transformers and painted the exact same Jet black.  Only this time the affect is  blue- ice peal fine metal flake and no Hammertone process.

These are an example of the fun I can have with creating something unique. These were designed to be mirror images of each other. I think the affect works quite well! Certainly mirror image mono-block amps aren’t anything new, but new for me.

These too are Kt-77 / EL-34 push-pull-parallel 100 watt per channel mono-blocks. These are units I made for my own stereo, since Ken took away my big purple push-pull-parallel amplifier a while ago. I just really missed having all that power. I don’t plan to sell these, but I’ve said that before. Anyhow, have a look….

The Candy Amp   6L6 P/P/P Integrated amp

After making over 50 amplifiers, your style, as a designer, takes on a life of it’s own.  You become very focused, and designs just seem to flow.  Over the past three years I’ve made some amps that have design features I really like.  This amp has all of those great features and some new ones I’ve wanted to try.    

It has dual tube rectifiers, integration, stand-by, and dual source inputs.  It’s all been neatly packed into a short 2″  chassis, for that sleek look.  Lastly, it has a few neat things I’ve wanted to include in an amp for a while like pinch tube retainers for the rectifier tubes, an A/C outlet on the back panel for say a CD player, and dual high voltage switchable capabilities for those of you who are Tube-Rollers.

 
So, here it is; a 100 watt per channel Push-Pull-Parallel 6L6 / El-34 / Kt-77 / 7591 / 7581 / 5881 integrated dual high voltage amplifier.  The middle switch on the left side panel allows you to switch from 350 vdc all the way up to 390 vdc as this power transformer has two high voltage taps.   This gives the user the ability to drive the El-34, 7591 or Kt-77′s where they like to be driven, and still allowing the user the option to drive those tubes at a lower voltage.   For the 6L6s 7581s or 5881s that prefer 350vdc, the lower plate voltage position would suffice.  This way you do not need to buy two or three sets of rectifier tubes that you would swap out to do the same thing, one set of 5U4 or 5U4Gs would work, but if you want, you still can tube roll your rectifiers too.  
Flip the same switch to it’s centre position and you have no voltage going to the tubes, and therefore the switch also acts as a stand-by.  The switch furthest back is a selector between two input sources, as there are two sets of RCA input jacks on the back panel.  The front switch is the On/Off and corresponds with a beautiful vintage ruby red jewel pilot light between the rectifiers.  On the back panel you have an IEC followed by an A/C  outlet, a source input (RCA jacks), the fuse, another source input (RCA jacks), the 4-8-16 impedance selector, and lastly the speaker binding posts. The volume control is located in the centre of the mirror as I usually do it.  
The colour?  Well, here it is painted a brilliant Candy Apple Red.  Believe it or not, there is no red paint used in this paint work.  It’s first painted black, then red metal flake is applied,… lots of red metal flake!  Then eight coats of clear is applied, and there you have it, Candy Apple Red!  With this many tubes, 13 to be exact, and this much power, the amp runs quite hot.  Perfectly normal, and well within the design parameters.  In fact, it can quite noticeably raise the temperature in a small room.  Perfect for a cool music room.  
This being one of my very best, most elaborate, and powerful tube amplifier ever, one should make sure he’s connecting it to a set of speakers rated over 100 watts each.  100 watts of tube power with all it’s headroom is a hell of a lot!  So, if you want a really powerful and versatile, integrated amp with huge Bling factor, this is your amp!  A one of a kind, the only one in the entire world in fact, signed, numbered, dated, and handcrafted by me.

Midnight Black    6550 P/P Power amp
Yes, It’s been a while since I’ve built an amplifier.  I took this summer off to enjoy the perfect weather, and it was perfect!  Hot, sunny, and not too much humidity every single day.
Now that summer has passed, and winter is fast approaching, I’m finding the need to build something new returning.  And just as fate would have it, someone else had been scoping out my work on my web site, here.
Seemed he’d been looking for over a year!  He couldn’t decide whether he wanted one I had for sale, or if he wanted me to make one especially for him.  He knew one thing though, he knew he wanted a Kt-88 / 6550.  He loved the tonal quality of the larger power tubes.  In the end it came down to needing to be able to switch from 4-8-16 ohm’s for his speakers, which the Firecracker amp doesn’t do, – it’s 8 ohms only you see.  So, we talked, and I designed, and he decided, and I designed some more, until we came up with what ended up being the perfect amplifier for him.  Here is the result of that process…
One beautiful Jet-Black with ice pearl metal flake 70 watt per channel Kt-88 / 6550 / El-34 / Kt-66  power amplifier weighing close to 40 lbs., and measuring 20″ x 9″ x 2.5″ high.  Capable of selecting from 4-8-16 ohms via a selector switch on the back panel, with Cardas binding posts and RCA inputs, along with an audio grade IEC.  Dual rectification is necessary here due to the high current needs of Kt-88′s and 6550′s.
Priced at $3,800.00  Sold.
So, without any further a-du, here is Anthony’s new custom amplifier…
 
The Balloon amp     6BQ5 P/P Integrated amp
Sometimes I design an amplifier around a specific component, and in this case it was this beautiful #80 balloon-shaped rectifier from the year 1931.   It is the predecessor to the 5Y3.  I’ve had this tube for over ten years in an old Attwater Kent console radio that didn’t work.  The cabinet was in nice condition so it was kept, but I couldn’t see trying to rebuild the radio when AM is nearly dead anyway.  In the end, the power transformer came in handy when I was asked to repair another old and more beautiful radio than this one, due to the 2.5v heater requirements of the radio.   
I’ve kept all the remaining tubes that were good and left the chassis intact inside the radio.  This beautiful #80 came from that radio and being the balloon type,  it’s somewhat rare.  The #80 in it’s regular Coke bottle format is not, so I felt it only suiting that the amplifier it goes into be designed around this tube, and here it is….

This is a very symmetrical and compact push-pull 6BQ5 putting out a modest 15 watts per channel.  At 300vdc on the plates, this amp sounds every bit as detailed as any of my single ended units with the power and punch you can only get from push-pull.  
It utilizes a pair of 12AU7 phase inverters, and hidden behind the left output transformer is the 6SN7GTB input tube.  A quad of 6BQ5s stand at attention in front of the Electrohome output transformers on either side of the amp, and last in the tube line up is the elegant #80 rectifier taking centre stage.  
I decided to make this amplifier an integrated unit, so no pre amp is required.  Just connect your CD player or whatever line stage device you have right to the gold plated RCAs located behind the 6SN7GTB on the back panel.  
A volume control located mirror central, as I like to do it, keeps the amp symmetrical and balanced looking.  The on/off switch is on the left side right next to an amber neon pilot light.  On the back panel you’ll find the speaker binding posts, a fuse holder, an IEC, and a switch.  This switch allows you to select 8 or 16 ohms for your speakers.  The output transformers had the taps, so I used them.

Plenty of power for the condo owner who wants a BIG sound in a small package, or the audiophile with those nice efficient Klipsch La Scala speakers who doesn’t need (or want) 30+ watts a side.  Believe me, when you get a chance to hear this amp, with its incredible sound stage, and presence, you’ll be quite amazed this is all coming out of such a little amplifier.  
The 6BQ5 tube, known for it’s beautifully liquid midrange is well represented, as well as deep bass and delicate highs partly due to over 1,400 uf of capacitance used in this amp.   This little guy sounds every bit as good and delivers as much punch as my biggest and most powerful amps, but at reasonable listening volumes.    Since this is an integrated amplifier and you don’t need a pre amp, you save.  
I built this amp to also appeal to those who don’t want to spend $3K+ on a power amplifier and then have to buy a pre amplifier to go with it, usually costing from  a few hundred to well over a thousand dollars.  Here you get both in one unit, and one less set of interconnects too.  There is another benefit to this.  With less components for the signal to go through, you have less degradation to the original signal.  This alone means you end up with a truer and cleaner reproduction.  
Painted a true Mint Green to go with its great Art Deco look, just like those old Catalin radios back in the 1930s and ’40s.
Priced at $2,200.00  Sold.

  
I knew this one wouldn’t be here for long.  There’s just something about the 6BQ5 that some people really love.  It must be its liquid midrange,except this one,as they all do no matter the power tube compliment, sounds just like all the others- perfect tonal balance.  
Brian had been watching my work for two years.  Saw me on TV, saw my write-up in the paper.  He knew some of my clients, and today he came over to demo a few, and fell in love with this one, so, he took it home.  Sometimes the best things are not so far-far away. A true old school audio guy, which is not to be confused with an audiophile. Brian, like myself, loves only vinyl and tubes.
 
Being a vacuum tube amplifier designer and builder has to be one of the best careers in the world.  I really do love what I do.

I normally don’t do this, but I liked the set-up so much that I thought I would share it – this is the Balloon amp in its new home, have a look…


The Black Knight       Kt -77  P/P Power amp

As with just about every client I have, one is never happy with just a single amplifier, they need to have another one, and Anthony is no different.  After owning the first amp I made for him for about five months, he just had to have a second unit, only this time he wanted a nice 6L6 / 5881 / EL-34 power amp to go with his 6550 / Kt-88 monster power-house.  

While this amplifier has been painted black at his request, it is a very different type of black than his last amp.  The paint used is a gloss Jet black, but instead of the ice peal metal flake in the clear coat, there is a very fine blue pearl metallic metal fleck in the paint itself.  This gives a very different effect and under the right light, looks very dramatic.  As you can see, the output transformers are massive!  They’re actually larger than the power transformer!  These were a rare find and were supplied by the client.  

I was more than happy to use them since I have never seen anything quite like them before.  Putting out a modest 40 watts per channel, these outputs are exactly what you would expect- sound wise when you couple large efficient output transformers like this, with a superior circuit like the one I use.  You feel like you’re right there in the recording studio with the artist or at the concert — FRONT ROW CENTRE.  

Coupling a great circuit with average parts will give you an amp better then most, but couple a great circuit with great components and look out, you’re in for a real treat!  The amp I have created here is an audiophile’s sonic dream!  Now, take that one step further by coupling this power amplifier to one of my new phono stage pre amplifiers, a good MC cartridge, some nice quality speaker cables and interconnects; you’ll have a  system that will bring you to your knees, really… I have one just like that!

The amplifier features Cardas RCAs and Binding posts on either side of a rotary selector switch to select between 4-8-16 ohms for your speakers, a 3a fuse, and an IEC so a high grade power cord can be incorporated.  
Even though I’m using a tube rectifier here, I added in a stand-by switch for pre-heating.  I feel it’s best for the tubes to be pre-heated and therefore the capacitors don’t see a spike in voltage while the indirectly heated cathodes in the power and signal tubes reach their prospective operating temperatures.  
Speaking of capacitance, this amplifier boast over 2,500 uf of capacitance.  Plenty for when an extra injection of current is needed for the power tubes.  A real treat for your ears!  And yes, it’s heavy!  About 47 pounds heavy.

Complimenting Angles    Kt-66 P/P  Power amp
A true Dual Mono, Stereo power amplifier

Staying current is the single most important thing every artist must be on top of all the time, but how do you stay current with 100+ year old technology?  Easy! You keep coming up with new attractive and unique designs.  This new power amplifier I just finished is a prime example of  design meeting necessity.  Let me explain…

Normally on any given stereo amp I build, you’ll see three transformers: a power, and two output transformers– one for each channel.  Now and then you might see a fourth smaller transformer, but that’s usually a filament transformer or a choke.  Here the forth transformer is another power transformer that is identical in every way to the first one.  Therefore I had to come up with a design that complimented the four transformers and their two different shapes and sizes.

The design idea here is what I like to call  “complimenting angles”; (I can’t think of a better phrase for it, so there you go).  The client who ordered this custom amplifier had a few requests on the design parameters which were as follows: 17″ long chassis, tube rectification, being able to see all the tubes while looking at the amp straight on, Kt-66 power tubes, 6SN7 input and phase-inverter tubes, and it could be any colour I wanted as long as it was black with ice-pearl metal flake (Now where have I heard that before?).  So, after trying different design ideas, I settled on the complimenting angles idea because it allowed him to see all the tubes while sitting right in front of the amp, and while pleasing and balanced to the eye, it stays in keeping with my usual asymmetrical designs.

Being balanced and symmetrical are two different things.  To me, a perfectly symmetrical design is predictable and flat-out Boring! Blah! Gag me!  Now take a look at this amp.~  The stepped design of the output transformers are mirrored by the rectifier tubes on the other side of the chassis.  While the power / pre-heat and stand-by switches sit unseen while looking straight on to the amp~  stepped in tandem right behind the outer most output transformer.

Having the power transformers side by side and at the back of the chassis keeps the weight even over the surface of the amp both visually and physically, while directing your eyes to the staggered outputs and then over to the opposing rectifiers.  Electrically speaking, having the power transformers at the rear of the chassis keeps the 60hz hum they produce far away from the sensitive 6SN7GTB signal tubes located near the front making this amp nice and quiet.   Neat!  It’s an attractive and clean look, don’t you think?

Now, back to why there are two power transformers instead of one.  You see, these power transformers and the outputs were originally on separate chassis as mono-blocks in an Electrohome console stereo.   Therefore, one power and one output transformer per chassis.

I know, these outputs are huge for a console stereo, but that’s what they came out of.  It just shows the high quality of the old Canadian made products back in the ’60s.  Notice the size of the power transformers?  Do they look rather small compared to what you see one my other amps where there’s only one?   This is a clue as to how much current each power transformer can deliver.  I could have used another, much larger power transformer to build this amp, but why?

I have two perfectly good power transformers here that where meant to work with these outputs, and to top it off, they put out the exact voltages I needed for Kt-66!  The only problem lie in the fact that one power transformer can only supply enough current for the mono block it was designed to power originally, not a stereo amp which requires double (2xX).  To fix this problem, why not incorporate both power transformers into a new design that is both aesthetically pleasing and electrically perfect.

In my mind, this was a golden opportunity to try something I’ve never tried before, which was to build a perfectly balanced true-dual mono stereo power amplifier.  Using two power transformers in a stereo set-up like this can introduce all kinds of problems with unbalanced voltages between the channels, causing volume, phasing and tuning issues.  I overcame these problems with a truly new and unique power supply circuit design.

The method at which I perfectly balanced the voltages for both channels while keeping them in phase is proprietary, sorry.  It functions accurately and is rock solid stable.  In the end, I built an amp that fit the client’s wants and needs and is the only one like it in the entire world!  I know my client will be blown away!  I am very pleased with this amp.

You ask, how does it sound?  Well, it sounds exactly like all my other amps do.   That’s why the tuning process is so important.  This tuning eliminates all those component tolerances, and brings the tonal balance to pin point accuracy, giving the amp my signature sound.

I really enjoyed making this one, that’s for sure!  So here is my latest Kt-66 / EL-34 / Kt-77 / 7591.  My only true-dual mono stereo  power vacuum tube amplifier rated at 40 watts per channel with separate power / pre-heat and stand-by switches.

The tube compliment is one 5U4G (or 5U4 if you prefer) rectifier for each power transformer, a trio set of 6SN7GTBs, and any one of the four power tubes I listed earlier.  All the transformers are Electrohome made in Guelph Ontario Canada.  On the back panel is an IEC power receptacle,  a 3a fuse,  a set of “push-in” speaker posts, two gold plated RCA inputs, and a rotary Ω selector to switch between 4~8~16Ω to match up with what ever speakers you like to use.   The chassis is 18 gauge mild steel with dimensions of 17″ wide, by 14″ deep by 2.5″ high.  And, as I eluded to earlier, it has been spoken for, and therefore not available.

Even though this amp is sold, there are still a few on the site that are not as of yet, or I can build any power or integrated amplifier you might like with nearly endless design parameters, it just has to thought up.  Once the idea has been conceived, I can make it happen.  If you like my work and would like a unit for yourself, send me an email anytime, I’m always more than happy to build something new!  My email address is eeamps@gmail.com

Prototype Phono Pre-amp

Here is a Phono Pre-Amplifier with the RIAA correction. This is the first of it’s kind for me and is a prototype. I plan to only make a select few of these. The unit you see here is my 3rd attempt at it and it’s perfect! This unit with one of my power or integrated amplifiers will easily out perform most if not all systems available on the market today in any price range.

This phono pre amp only has an On/Off switch and a volume control for the user to select, no tone controls of any kind here! Since the unit has such great gain capabilities, you can use either MM or MC phono cartridges with it. The unit also incorporates a separate power supply with a 3′ cord connecting the two units together. This ensures no noise from the power supply reaches the high gain stages of the pre-amplifier.

Built as a custom unit for a great customer and painted his favourite ‘Firecraker Red’ with ice pearl metal flake.  Sold.

Prototype 2 Phono Pre-amp

 There is no substitute for that clean vacuum tube sound. That means you MUST use vacuum tubes throughout the entire amplification process, from the phono cartridge all the way to the speakers. Here is the phono pre amplifier I built for my system. Painted in a stunning Emerald Green this pre amp is considerably smaller than the first one I built. As you can see, no tone controls, only a volume / balance combination and a mute switch.   A separate power supply to ensure no noise makes it to the very sensitive phono stage pre amp. And like the first phono pre amp, you can use either MM or MC cartridges

Just a word on my phono stage pre amplifiers,…

They will only be made available for those who already have either one of my power or integrated amplifiers for compatibility reasons.  These are highly sensitive units, and may pick up unwanted noise from a foreign made power or integrated amplifier or other related source.  I know they work very well with my components and I also like the idea of rewarding my existing clients with an exclusive offering that only they  qualify for, if they so choose.

Now, here’s a look at how my personal stereo system looks today.

I’m using my new pair of EL-34 mono block power amps with my phono stage pre-amplifier & separate power supply.   Along with my 1977 Sansui SPx-9000 speakers and my 1977 Pioneer PL-570 turntable with an audioquest MC cartridge.

I’ve added a cartridge loading selector switch on the side of the phono preamp so that the phono cartridge can be load corrected by selecting either 100 ohm, 200 ohm, 420 ohm, 1k ohm, and 47k ohm which is the standard for MM.  Since I’m using a MC cartridge I have it set at 100 ohms.

This selector switch can be switched on-the-fly as well, and by trying the different settings, you can “tune” it by ear.  Mine sounds best at the 100 ohm load setting.  Cartridge loading is a balancing act, you want just enough resistance to keep the coils inside the cartridge stable, but not too much that you restrict their ability to move freely.

Your ears will tell you which setting is the right one for your cartridge.   The speaker cables are Cardas Golden Cross and the interconnects are Monster Sigma.   I do use a power conditioner to keep out unwanted line noise.    As with everything in life, it keeps on evolving, and only getting better as we learn.

The 1966 Empire Console Stereo

Every artist has a piece that he is most proud of.  Call it his legacy piece.  Well, this is mine.  Ever since I was five years old I wanted a console stereo.  My parents bought me a HiFi to shut me up, but the HiFi wasn’t stereo, and I knew the difference.

I loved my HiFi, but when the opportunity arose, I would listen to our big console in the living room.  I loved to climb onto the ledge to see the Garrard Type A turntable work.  I so much wanted that stereo.  My Mom eventually gave it to my Grandfather and I was pissed!  I said to my Mom as I pointed my finger at her, “One day I will make my own stereo, just wait and see!”

Well, almost 40 years later I did just that.  I made my own.  My Mom passed away only two years before I was able to build this project, and I know she would have loved to listen to it.  She would have got a good laugh out of it too, as she often spoke of my hissy fit over her console stereo.

You know, I probably would have given it to her as a gift.   I can just see her enjoying it now.  She loved music.  Anyway, I’m sure she’s heard it many times and loves it.  Her old saying about me was “What Steven wants, Steven gets!”  I guess that’s true.

So now that I’ve explained why I wanted to do this project, here is the result of my promise.   Here is my version of a 1966 Empire console stereo.

First I took a pair of identical cabinets made by Magnavox and added height to one to accommodate the height of the turntable, and shrunk the other one to create a satellite speaker that can be placed anywhere in the room and spaced far enough away from the main system to create the true stereo affect.

Next I had the two cabinets painted Jet black with ice-pearl metal flake in the clear coat to give it that 1960′s look. Next I took a 1960′s Garrard Type A turntable and re-built it to it’s original splender and instead of hiding the tube amplifier inside the cabinet, I placed an 807 power tube amplifier right next to the turntable for all to see, because to me, tubes are beautiful!

The speaker compliment are a set of Jensen 15″ drivers and a set of DeForest 3″ tweeters.  The entire project took two months to build and two weeks to accurately tune.  Not only did I have to tune the power amp, and the phono preamp’s RIAA, but I had to tune the speaker crossovers as well.  It’s a lot like cooking.  A little bit of this, and a dash of that, and there you go!  Perfecto!

This console will stop you in your tracks!  The end result is a stunning looking 1960′s piece with killer sound!  I have to admit, I surprised myself!  And if the truth be known, I listen to the console more than my main system.  It makes me feel like a kid again as I watch the Garrard turntable do it’s thing, but it’s how it sounds that keeps me wanting to listen to it as much as I do.  It was a long time in the making, but well worth the wait.

Here is the result…

I have a couple of videos available showing the console…

  1. Steve – so glad you’ve set up a blog to share your work! All of us here love seeing your latest projects. You hit the nail on the head when you called it ‘your art’….it most definitely is art!

    -Pat

  2. Congratulations, Steve, on a beautiful blog site which is every bit as professional as the work you create. I have thought of your amps as true art work since I saw the first pictures you sent me…

    I wish you every success with your art and trust that your passion will be recognized by a much larger audience now that they can see the results of your labour!

  3. Lance Cochrane Says:

    I’ve said a number of times that a teacher should be judged by the quality of his students. A good teacher should have students that surpass him. Steve is well on his way. That’s due to his hard work and innate curiosity. There is a sense of style to his creations that many designers lack. This is really only the start of the adventure. Check back in a few years to see where it has gone. Expect some intriguing surprises.

  4. Bob Carver Says:

    Beautiful! You are clearly having too much fun – building amps is the funnest thing in the world. Gorgeous works of art too!

    Good luck, warmest and best regards,
    Bob Carver

  5. Mike Demir Says:

    This is the best sounding and most beautiful amplifier I ever owned, I like the sound quality of this amplifier, lot of musical detailes, excellent bass, mid’s and hi’s with realistic soundstage.
    I can’t thank you enough Steve.

  6. al mcgregor Says:

    Take it from one very happy customer: Steve White’s Amps will not only spoil your ears, but make your hair stand up and your face tingle a little bit. Powerful stuff !!! Thank you Steve !!!

  7. Jim Driscoll Says:

    I recently acquired one of my friend and neighbour Steve White’s 6L6 amplifiers. While I had some experience years ago with vacuum tube technology (my father was an air force electronics technician) I have not had an opportunity to listen carefully to a tube-based amplifier since the 1960s.

    Through the 1970s and 1980s, when budget permitted, I followed the equipment reviews in The Absolute Sound and experimented with a variety of solid state amplifiers, tape decks and speaker systems. I eventually settled on a system that would reproduce music cleanly and effortlessly (what used to be called the New England sound), but still have enough oomph to handle symphonic recordings and my wife’s hard core rock and punk collection.

    I was blown away by Steve’s power amplifier. I separated the preamp from the power amp in my Yamaha AX-592 integrated amplifier and hooked up the tube amp to my late 1990s vintage Paradigm Monitor 5s. What had been a clean but rather dry system opened up both sonically and spatially.

    The imaging in Steve’s amp is incredible–spatial imaging both left to right and front to back is the best that I have ever heard, and the articulation in the bass and mid-range is superb. I can now hear the kick bass on a drum set in the background of some of my favourite rock and blues recordings.

    Generally, as my wife put it, what we have now is a system that fills a room with natural-sounding and well balanced sound, and we are now working our way through what sounds like a completely new music collection.

    Steve is a superb craftsman. The build quality of his equipment is impeccable, and the design shows a considerable flair for what will be both striking and attractive. I don’t have the technical chops to evaluate his electronic innovations, but I can testify that the acoustic results are extraordinary. I have already signed up for listening tests on his next generation of amplifiers.

    Hi Steve:

    I saw and listened to Jim Driscoll’s unit yesterday. I was quite impressed. I had no idea my neighbor was doing such great work. I’ll have to drop by your shop and see you in action.

    Jim

  9. Hey I own 2 of Steve’s amps and I love them both!!

  10. Jim Driscoll Says:

    Update on an earlier post…

    I knew that the preamp in my Yamaha AX-592 integrated amplifier was not its strong point, so I hooked up a NAD C162 preamplifier (Class A, solid state) and a set of Audioquest Sidewinder interconnects to Steve’s amp and my NAD C520 CD player. The cables are still burning in, but what a treat!

    Steve’s amp is sounding better and better, and my Paradigm Monitor 5s now have beautifully controlled bass output that the heavily damped Yamaha amplifier never could manage.

    When Clive Davis ran Columbia records, he favoured the Columbia sound–exaggerated highs that matched up to the middle-of-the-road phono cartridges that were sold in the 1970s. When he took over Arista records in the digital era he (unfortunately) kept the signature sound and many of his CD productions from the 1980s were painful to listen to on my old Yamaha system. Tube technology and the NAD sound have solved that problem, and as the system burns in the results are exceeding my expectations: a realistic sound stage and wonderfully articulated vocal and instrumental sound across the full spectrum.

    The system has even dealt successfully with my favourite torture test: Ry Cooder’s “Get Rhythm” album from 1987. The title track demands a system that can sort out a bewildering variety of high-frequency and mid-range sounds. I recommend the album to anyone who wants to push a system to its limits.

    You see, this is what makes it all worth while for me, when a customer takes the time out of his day to post what he thinks about my work! I knew Jim would love owning one of my amplifiers, as he is an avid Audiophile, but I never expected this! Jim is the quiet type who tends to keep his opinions unknown. Jim is one of our local University’s Professors in the sciences here in Peterborough who’s true thoughts seldom leave the auditorium.

  12. Very nice Steve!!! The paint jobs are fantastic! All the inputs and outs are on the rear of the amps where they should be. Very professional. Ever see one of those amps someone slaps together on eBay and has the inputs in the front, who wants that nonsense? These amps are the real deal. Why anyone would spend 2k plus on a McIntosh I’ll never know. The circuit Lance taught us beats every single “high end” tube amplifier it’s put up against, hands down.
    You are a true artist indeed.

  13. glassart1684 Says:

    Thanks Jim, coming from you, those words mean a lot to me! We, as students of Lance’s have been given the knowhow to create the best possible vacuum tube amplifiers available at any price. Ask any one of my customers and they will tell you the same thing!
    I have also read comments that Jim’s customers have posted, and they love their units more than anything they’ve ever owned. Jim has his own creative flair and his build quality is top notch! We can only thank our teacher Lance Cochrane.

  14. Larry Van Wormer Says:

    I recently purchased an amp from Steve, a single ended version using 807 output tubes (It’s the blue one currently in the images Steve has on his site.) In sum, a wonderful amplifier!

    While it’s strong in all areas, with very good bass output, the characteristic I like best is it’s very good dynamics. The music is getting very close to “live” now. For instance, plucked strings and percussion, even at low levels, sound very realistic. Voices are a major strength as well.

    I continue to be surprised at the sheer volume of clean sound the amp can produce on demand. And, with it’s great dynamics, the music sounds lovely at low levels too. In fact, I think I’ve reduced my usual listening levels, just because the sound is so satisfying at low levels.

    So, lots of good characteristics, with no faults. I’m very pleased to own this amp!

  15. I have been listening to music casually and seriously since 1964. The older I became and the more money I acquired; this affluence was generally reflected in increased expenditure on music reproduction components.

    I would shudder to think of what I have spent on audio reproduction components and, would be probably be shocked at what I have spent on music source material – be it 45 rpm single, cassette tape, 8 track, vinyl, CD, HDCD, SACD, Direct to Disc Vinyl, Laser Disc, DVD Audio – I think you understand.

    There are a few music releases over the years that I have come to cherish – in all formats. They are old friends and have gotten me through the best, the worst and even the most mediocre of times. I know them well – or, I thought I did.

    I had an opportunity recently to audition 3 amps that Steve White had designed and realized. After listening to all three I knew that I would need to re-introduce myself to my ‘old friends’. So to start that re-acquaintance, I purchased one of Steve’s single end amp designs.

    My system has never sounded as good as it does now – I am hearing things in ‘familiar music’ that I have never heard before.

    This may be the first Steve White amp I have acquired but it will not be last.

    Steve has rekindled my interest in ‘serious music listening’ with his sonic architecture.

    Welcome back to the future – analog!!

  16. gerry gregg Says:

    I have a vintage mid 60′s Traynor YBA-1 Bass Guitar amplifier which had degenerated to a point beyond useable. I have, in the past several years, had two different “highly recommended” amp technicians service and repair it. Each repair lasted only a brief amount of times and after having been worked on by each technician, the amp failed while I was playing gigs.
    I met Steve and started chatting about his work and the amps he was building. I suggested that he might look at my dear ole’ amp for me if he was interested and he graciously agreed.
    To make a long story short, once we got the amp opened up it became glaringly obvious that my amp had been very poorly treated by the previous technicians and that there was much wrong with a once beautiful amp.
    Steve agreed to take on the job of bringing it back to life, despite the fact that this is not the kind of work that he normally does and work that I expect falls fairly far below his skill level.
    Within two days Steve called me to say that the amp was up and running and was very excited for me to pick it up, take it home and play it and let him know what I thought.
    The result was an amp that sounded far better than it had the day I bought it 15 or so years ago and probably sounds as good as, if not better, than the day it was made. I was, and am, thrilled by the results of Steve’s craftsmanship and am so grateful for his very generous work.
    As much as I was impressed by Steve’s abilities in restoring/rebuilding this classic amplifier, I was equally impressed with his professionalism in every aspect of my dealings with him. It is a very rare thing these days to encounter someone as devoted to both their craft and to the complete satisfaction of their customer as is Steve. I am very grateful for the craftsmanship, professionalism and generosity that Steve showed me and I have no doubt that all these qualities will serve both him and his customers throughout a long and prestigious career.
    I also had opportunity to listen to his amplifiers and would not hesitate to say that I have never heard better sound from any stereo amp.
    Thanks and best wishes Steve…

  17. I met Steve by chance in a local shop and I was so taken by his passion for his work that I just had to audtion his amplifiers. Intriging designs with unique artful presence, but the shock was the performance. I purchased one of his 6L6 push-pull amps.
    My sytem has never been so musical, spacial and most importantly Organic, for the first time in years my system is capable of raising the hair on the back of your neck. Female vocals have a very uncanny clarity and realism, strings never more complete and natural, right thorugh to the wood of the body. What really took me by surprise was the fact that it was capable of impressive impact and speed in the bass while retaining the forementioned grace. Well done Steve! I’ve sold my old tube SET and solid state amplifiers, no turning back.

  18. Your amplifier told me how good it is immediately. Over the next 150 hours of listening it told me how good parts of my system are not. Your amplifier is so good that it drove me to improve my front-end setup, right down to the wall outlet plug. The amp sounds good mated to anything. Optimize the system, however, and the sound is absolutely jaw dropping.

    As well refined audio components do, my 40 watt 6L6 amp reveals the emotion and substance stored in the record groove. It adds nothing to the signal; the critical tonal balance and integrity of the original source remains. Nor does it take anything away from the artist’s intention. Yes, it delivers all the sonic attributes of audiophile lore…transperancy, detail, holographic imaging, blah, blah…but most noticeably it delivers the emotional impact and vitality of the music. It’s real and it’s unmistakable. Music sounds likes music, so much so that the tenth hour of my listening session is as enjoyable as the first hour.

    During the last two decades I’ve had the fortunate opportunity to audition many of the revered names in vintage and modern tube amps. Without hesitation I can tell you that I would buy my amp again tomorrow morning. Steve, thanks for my amp and for the new record collection I’ve owned for years!

  19. I’m not a hardcore audiophile with a golden ear, but a regular Joe who has always loved music – loved it in the sense that it provides impetus for my life – it’s a need for me. Like many who “need” music, who fall into it and live there for a period and become rejuvenated by that, I become irritated, bothered by poor sound quality. For this reason I judge audio equipment almost entirely on how quickly it takes me to ‘fall into’ the music and how deeply I do so and how hard it is for me to be jolted back out of that happy place. I don’t worry overly much about stats or tonal balance or how much my cables cost or how liquid the mids are or blah blah blah. I listen for the music. What lets me down is when the sounds jolt me out of the music. This is where Steve’s power amp has really transformed things for me. I’m very happy with my speakers, and my turntable is solid, but I had been using a cheaper entry level integrated amplifier. Steve’s power amp combined with a Sonic Frontiers preamp has done something for me that I wasn’t sure was ever going to happen – left me satisfied. When I put on a record now I’m always able to just slip into the music, almost immediately. The ‘sounds’ coming from my stereo never interfere. The music is balanced, smooth, clean and clear and to me, sounds just like it was intended to. The imaging is fantastic, the bass is controlled and yet organic and the separation between instruments is excellent. All in all this is the amp I plan to keep for life, unless I buy a more powerful amp from Steve, and for me that is a wonderful thing as the audio equipment game was always about the end result and not the journey for me – now I can spend my money on records and my time listening to music, happily.

    On top of all my love for the amp, Steve was and continues to be a fantastic guy to deal with in every way. Extremely helpful, honest and forthcoming he made the whole process really fun and several months later he continues to offer me advice and assistance that is invaluable.

    If you are a genuine audiophool you owe yourself a listen to one of Steve’s amps and if you are, like me, more of a music lover without the time/money for endless upgrades one of his amps can provide an excellent starting point or basis for a system. Either way I recommend to anyone reading this that they try one out.

    I am into tube gear and have been selling tubes on ebay for close to 5 years. I sold some transformers to Steve on ebay a couple of years ago and that is how we met. We have been corresponding ever since and have become very good friends.

    I have had a number of tube pre-amps but I was getting tired of the sound of miniature triodes. I had some excellent high end 12xxx units and had hit a dead end with them. I wanted a simple pre-amp that used some of the larger triodes like the 6SN7.

    I made a request to Steve for a simple but high quality 6SN7 pre-amp, and with a couple of weeks he had one built for me.

    What I received was absolutely incredible! Such a simple unit, only a volume control, but what a sound! My heavily modded Dynaco ST-70 and B+W 604s speakers came to life with a sound that was out of this world.

    I will never go back to the smaller 12xxx triodes in my system. The pre-amp Steve built me is rock solid and high quality!

    Many thanks Steve for the incredible sound experience!

  21. Hi Steve. I caught your spot on Chex TV tonight. It was very interesting. You do amazing work. I am going to show this site to my husband; he will appreciate what you do. Am also emailing your link to my son. He is a musician living in Toronto. He will definitely think your stuff is excellent! Keep up the good work; you are on to a really good thing!

  22. I thought I left a comment on this site some time ago. One has to call your amps the “art of the state”. These are electronic pieces of art IMHO. I would not doubt that they sound wonderful as well. I would put one of these units on a 5 channel dynaquad circuit and believe it would be a feast for the ears. Some of the amps you produced are the most unique that I have seen manufacutured by anybody. As Tony the Tiger would say; GREAT!!.

  23. Steve… just wanted to let you know I re-visited your blog today and your work just keeps getting better and better. I am so happy that you have found your true passion and have found a way to demonstrate it to the world through the beautiful work you produce, both from an audio and aesthetic perspective. Keep up the amazing work and congratulations on producing such awesome art for the ears and eyes!

  24. Steve, I love the new stuff. That little one shaped like an engine is amazing. My brother recently visited from BC and saw my amp for the first time – as an art aficionado I knew he would love it and he was floored – loved the sound, loved the look and is determined to own one someday.

    Good stuff, hope to see you around soon,
    Adam

  25. Hello Everyone
    I am the proud owner of what must be considered one of the world’s best Amplifiers. Steve White’s Purple 80 wpc push pull parallel 6L6.
    I feel very fortunate to have found Steve, as his work is top notch and he is a class act. The absolute clarity, power and sound stage of this amp is simply astounding! I also had the pleasure of auditioning two other amps besides the one I bought, Flash Quattro- very nice, also the 6550 Firecracker amp. If I had the money I would have come home with the Firecracker amp as well since it was also fantastic. My main speakers are JBL Professional 4333 monitors and my new amp makes the system sing better than any system I have heard in my lifetime. I have heard many systems and even worked in the industry but nothing compares to the Steve White amp along with my JBL’s. If you are reading this, do yourself a favour and buy one one of Steve’s creations, I guarantee you will not be disappointed as this is world class stuff. I can’t wait to blow away my audiophile friend with his fancy Krell amp and B&W’s. Thanks again Steve you rock!.

  26. WOW! Just wow! Totally 100% epic win.

  27. I love my amp and can’t see myself ever parting with it in fact I have had the thought that if my house burned down or a war broke out I would save my amp!

  28. Was just reading through the site again – I’ll have to make sure I stop in and eat at Black Beans in Port Hope – good food and good sound are my two favorite things :) If the owner drives a subaru I’ll assume they are a long lost brother/sister.

    Beautiful new amps Steve!

  29. Wow,… where do I start. I have known Steve for sometime now. We met through Canuck Audio Mart where I was selling some transformers. Steve had purchased them and I mailed them up to him. I have family in Peterborough, so on one trip I made arrangements to meet Steve and bring him more transformers. I purchased one of the two Black stereo 6BQ5 amplifiers Steve built. Truely amazing pieces of art. Not only did it look fantastic, but it made my Altec 604-8G’s and Stephens Tru sonic 150CX’s SHINE as never before.
    Steve then built a single ended 6BQ5 amp that came into my possession, and with no surprise, the same results on the same said speakers. In time I will get Steve to build a 6V6 and a KT66 amp for me.
    I have had the privilege of auditioning a few of Steve’s pieces at his residence such as the amazing 807 console all hand built and his latest EL34 6CA7 Killer Mono Blocks. Anyone purchasing those puppies will be BLOWN AWAY, and I mean it!
    Not only do Steve and I have a business relationship, but I consider him a good friend as well. I will bring the beer next time as I had his last one last visit.
    Keep up the creative artistry and sonics!!!

  30. Steve custom built the jet black 6550 amp with pearl metal flake for me. I received it a few weeks ago and only this past week really had a chance to spend time listening to it and putting it through the paces. At first it had a bit of a 60 hz hum to it, so I told Steve, and he suggested a few things but finally decided to drive to Pittsburgh, PA (an 8 hour trip by car) to fix it himself. And fix it he did. It turned out to be a tube. It was a pleasure to meet Steve and spend the afternoon talking stereo and amps with him. If you ever have the chance to spend time talking with Steve, don’t pass it up. He’s not only knowledgeable, he’s the kind of person you want to spend time with. I was sad to see him go. And the fix was pretty simple and now the amp runs dead quiet and sounds wonderful. Lots of headroom. Deep, controlled bass. Glorious mids and highs. It’s been one of those experiences for me where I want to listen to everything I’ve loved in music all over again, and I’ve been doing just that all morning. What an amp. Those 6550s are my tubes of choice. I know that Steve’s teacher isn’t fond of power (he’s told me so himself in emails), but the power along with the capacitance that Steve builds into his amp makes this a fast amp, recovering quickly, at ease with a complex, quickly changing signal. One of my tests is a Roy Buchanan live CD–Amazing Grace–that has Buchanan’s version of “Green Onions” on it. He mixes organ, bass, drums and his exquisite, constantly shifting guitar into a 7 minute track that challenges amps to keep up with the sudden shifts and mixes of organ and guitars. My new amp loped and danced along with that track. Really superb. Every instrument clear in the image. I listened to it twice this morning just to hear the tonality and clarity again.

    Most of my experience with audio has been vintage integrated, power amp and mono block equipment–Scott, Dynaco, McIntosh, and Marantz–although I have owned relatively new equipment as well, most of that being McIntosh. I kept my McIntosh C2200, which is running now with my 70 wpc amp that Steve built, and they’re a great match. I’ve had this pre on MC 275 Mark IVs and Vs, as well as on the 2102 (which I liked a lot), as well as on a bunch of solid state amps, including McIntoshes. To my ear, the only one of these amps that I’d say is in the same league as Steve’s is the McIntosh 2102, and that’s got tons of power as well and run 6550s (which can sound harsh in some amps). In fact, I was going to buy a 2102 until I came across an amp that I bought from Lance Cochrane. When I found out that Lance was Steve’s teacher, I started to think seriously about having him custom make an amp for me. That was a year ago, and after a year of thinking, now it’s here.

    My obsession is speakers. I’ve gotten into rebuilding them and helping a friend build them. Right now I’m running this set up with rebuilt JBL speakers. I like the L80T and the 120ti with new batting that mostly wool, Illinois and Kimber caps, Erse NP electrolytics, copper wire, and Cardas binding posts. Over the years, I’ve owned a lot of speakers and have rebuilt most of them. My favorite speakers of all times that I regret letting go of everyday were built by Joachim Gerhard. I’m taken with simple 2 way bass reflex speakers and loved his Allegrettos. I don’t have the money to try his more expensive speakers but these were not cheap and would I ever love to hear them with Steve’s amp. But these old rebuilt JBLs sing with this amp and the McIntosh pre. My CD player is a Raysonic 128 with Underwood mods so it has a fast clock, good caps, and Ediswan 6922 in both the balanced and regular lines. Great music with these pieces and this 6550 amp.

    The other part of my story is that when Steve was here, I mentioned, as I had to Lance almost a year ago, that I have this Eico HF 89 (50 wpc, EL 34) amp that I really like but it keeps blowing tubes. Lance said he’d rebuild it, but we decided it weighs too much to ship back and forth, so Steve saw the IRON, and I do mean IRON, on this amp. No one I know has ever seen output IRON as huge and the ones on that Eico. So Steve took it to rebuild with his own circuit and 6550s. We both can’t wait to hear what it sounds like. He’s going to keep the old case but it will completely rebuilt. Stay tuned for an update on that.

    When I get a piece of equipment like this amp, all I want to do is stay home and listen to it. And that’s what I’m going to do now.

  31. You are an artist of the highest order. Unbelievable workmanship and what better interest could you have than tubes. ;)

    Cheers!

  32. Lawrence Sandler Says:

    I have an amplifier built by the renowned Lance Cochrane and needed someone to troubleshoot an issue. As one of Lance’s apprentices, I’ve been following Steve’s work and asked Lance to reach out to Steve to take a look at my amp. Steve was all too willing and I sent him the amp. Within a day, the problem was isolated and the required components replaced. Steve was a pleasure to deal with and cared enough about one of his Teacher’s clients that he did not charge me for his time or replaced components. Steve has a new client – Lance is ‘passing the torch’ and I will without question purchase my next amp from Steve White.

    Thank you Steve! And thank you Lance Cochrane for inspiring him.

    This tube site is an inspiration for someone who enjoys building tube amplifiers. It is great to see that the art will remain alive for years to come. Tubes will never die!!!

  34. Beautiful work! I have an old Halicrafters SW radio that runs on the old VTs. I also have a selection of old (but unused) RCA tubes that go back to WWII. I just don’t have the knowledge or extra parts to make an amp. Oh..I wish I could afford your stuff…but someday..someday…

      Hello Sir, and thank you for your great comment on my work. If you are in the area, please feel free to contact me so that you may come over for a demonstration. I love showing my work and letting new people listen. A lot of R&D has gone into what you’ll hear, and I have yet to hear anyone tell me that they’ve heard other amplifiers as good as what I’m making. Really, for the quality of both build and sound, my amps are very reasonably priced. I have many clients who have sold their old high-end amplifiers after buying one of mine and come away with more cash for their old unit than they paid for mine, and mine was clearly the better amp! Happens all the time.

  35. Anthony Petrosky Says:

    It has been months since my 40 w 6L6/5881/EL-34/KT-77 arrived. When it did arrive, I immediately took the 6550 70w amp that Steve built out of my system and listened only to the new 40w. It ran every day, sometimes for only 10 minutes, but often late into the night. I tube rolled everything it’s capable of running until Steve suggested I try KT-77s. Never heard of them but I ordered a quad from TC tubes (my favorite tube dealer–gorgeous, clean tubes) and couldn’t believe my ears. I’m not a fan of EL-34s, as Steve is, and his comparison of the KT-77s to the EL-34s put me off a bit, but these tubes are nothing to my ears like the EL-34s. They have depth and tight bass, unlike the EL-34s, and in this amp, they sing as the now permanent resident power tubes. Hearing those tubes got me to thinking about switching in some 6SN7GTAs for the GTBs I had put in originally. TC tubes delivered some NOS Sylvania 6SN7GTAs and I put in three of the quad. I have to say that I’ve never heard a tube whose variations matter as much as the 6SN7. I’ve tried almost all of them including the holy grail Tung-Sols, which I didn’t like, and have decided that Steve is once again right. The Sylvania 6SN7GTAs are absolutely the most musical low noise variation of this tube. So they are now running in the 40w amp along with a Mullard NOS GZ-37 rectifier. It’s a very cool tube. Five inches tall. Flashed blue for new when I first put it in. That’s the tube set in the 40w. As far as I’m concerned, it’s perfect. I haven’t yet said anything about the sound of the 40w amp, and you know from my previous post on the 70w 6550 Steve built that I love the sound of that amp, so bear with me because rolling those tubes got me to thinking about the Telefunken 12AX7s in my MacIntosh MC2200 preamp, so I switched those about with Amperex with the dimpled getters and switched out the 12AT7s with NOS Siemens that I bought from TC tubes. Whew. What a difference in the preamp. Those holy grail Telefunkens can’t compare to the Amperex with the dimpled getters. They’re tinny in comparison to the richness of the Amperex.

    All that said, the past two days I’ve had time to play with both of my amps. So I had a few audiophile friends over, a couple of them own amps and systems I could never afford, and we A/B compared the 70w 6550 running NOS KT-88s from the 1980s and the 40W running new KT-77s. We tried acoustic, Anouar Brahem–one of my favorites for the Oud and accordion and piano–, and classical–Glen Gould playing the French Suites on a Master CD, and even some Rolling Stones. We played CDs for most of the day and night. Finally, one of my friends says, “I’ve got it.” The 70w, as rich sounding as it is, is just slightly less detailed than the 40w. Must be those output transformers, he said. We all more or less agreed with him. It’s astonishing how difficult it is to hear the difference. That 6550 still heats up the room and the 40w runs cool. I should say, too, that since I wrote my entry about the 70w, I’ve sold all those speakers I rebuilt and now have one pair of Harbeth Super HL5s that I love for their detail and mid-range and tight bass. They’re not full range speakers but you’d never know, especially with the kind of music I listen to.

    What’s the final verdict? I’m glad I didn’t give my son the 6550 as I planned to do. It puts a little bit more “heft” into the sound stage, and it seems a bit more commanding to me, but the 40w with the Kt-77s is more musical in the mid-range, and I think it’s because of the tubes. I finally don’t care for the flatness of the 6550 so went with the KT-88s that to my ear are more musical, but the circuit of this amp, along with the KT-77s really sings in the mid-range, and to me, that’s the difference between these two amps.

    Well, here we are. I spent an afternoon with Steve listening to our music (aka, age group) I am totally blown away with what can be done with what Steve does. We listened to alot of music. I was so wanting one of his amps that I bought it on the spot. It is my starter tubeart amp. So far I have had it on my mainspeakers, new speakers, old vintage speakers., And it does perform. It realy likes my Dual 1019, with a set of new studiolabs. Clear, clean, So much openess. Before it was so muffled through my old fisher 800c receiver. Steve went through my likes, guitar, and boy did we hear guitar. I am by no means an audiophile. I like his Sansui’s hooked up to a high end system.-THATS ME! I try everything for that music that we hear, not a high end system from a high end shop. I want to hear the music, Thanks Steve for showing me the way. I will be back. The 807′s are a mean lookin unit. See you when I want more of a well built unit, only with 807′s. They look like they rock , I want rock! Cheers

    I must say that Brian and I see eye to eye on so many levels. He knew exactly what he wanted and so did I. I knew he was completely absorbed in the music I was playing for him. I knew he had never heard music reproduced this well ever before. Brian couldn’t believe how much of the music he had been missing all these years. This is exactly why I’m into this as much as I am. When I see the total disbelieve in the sound quality and tonal perfection I try so hard to achieve- in a potential client’s face, I’m completely beside myself. And when they drop the cash down right then and there on one of my units, it’s the best feeling of accomplishment I could possibly want. It was my pleasure showing Brian the way…

    I found Steve through word of mouth here in town, and am so glad that I did. My old Marshall stack and I have a long history together, so when it started dying out on me, I wasn’t prepared to simply toss it aside. I had already taken it to two others shops for repair, to little or no avail, when a friend showed me a clipping from the local paper featuring Steve White and his work.

    In short order, Steve had my ol’ Marshall head and cabinet singing to me sweetly, just like it used to be. He did most of the work right there in front of me, and I could’nt help being struck by his inside-out knowledge of tube amp systems, and his unyielding insistance upon quality, both in parts and workmanship. I guess it’s true… 3rd time’s the charm!!

    thanks Steve, have a great Christmas!! :)

    27 years is a long time. That was the last time I saw Steve, a unique student, as he launched himself into the world of work. He was unique because he could focus on a challenge that interested him and see it through to fruition. He built a working model of an elevator and won second prize in a regional science competition.
    Little did I know that Steve’s interest in electricity / electronics would have him one day building vacuum tube amplifiers for the love of the technology.

    We met and spent four short hours just catching up on where our lives have taken us. He totally embarrassed me when he presented me, as a gift, one of his hand crafted power amplifiers in appreciation for believing in him and encouraging him. I will always treasure such a valuable gift that can be enjoyed every day.

    The sounds that emanate from Steve’s power amplifier are full, rich
    and mellow with all the resources necessary for those fortissimo notes and chords when required. He has taken vacuum tube technology and coupled it, with his creative talents, to produce a hand crafted, robust power amplifier that any owner would be proud to own and showcase. His dedication to personally hand wiring and assembling each amplifier speaks volumes (pun intended) about him as a person. He has a niche business, EMPIRE ELECTRON AMPLIFIERS, that is sought out by those seeking the analog sounds of the vacuum tube. A great pleasure to hook up with him once again!

    I found your site , after looking for circuits using various valves. I must say that after seeing your amplifiers, it bought me out in a very hot flush. These are wonderful pieces of work not only in performance but in looks and style. For many years, manufactures have tried to hide everything until we just get a plastic box that makes a noise, and a noise is all it is. and after a couple of years when it breaks, they will go and buy another box that just makes a noise. your designs are not only just good to look at, but sound good as well. and will perform for many years to come, Recently, as an electronics engineer, I came across a 1954 KB radiogram that had been standing in the garden for four years, all be it wrapped in clingfilm. Expecting the worst, I removed the clingfilm only to find that the cabinet and felt lining were in perfect condition. I then decided to power the unit on the veriac, and low and behold the unit came up and worked perfectly well, apart from some mechanical defects with the turntable the electronics side sounded good. try a modern day stereo after 50 years, Keep up the good work you are an inpiration to us all. Thankyou, Pete Martin UK
