Eico HF-20 monoblock rebuilds
Classic units.. Simply stunning, can’t say enough about these. Gutted the old tired original caps and resistors, used my circuit , painted and trimmed with nice walnut. Check out that output transformer.. Classic. Also ditched the small stock power trans for a larger one. Gives 420v to plates and screens, Ultra-Linear mode. KT88, 6550, EL34,KT77 AND KT66 type power tubes can all be used. Plenty of power, easy 50 watt each amp. Individual power tube bias, no adjustments needed, no adjusting bias, hum or balance needed. plug in and listen. Email with questions. Asking $2500 for the pair. top view.
Guaranteed to be some of the best sounding, best built tube amplifiers out there today. All handwired and made right here in the USA, as it should be, just like the good old days when these babies were new!

Send over an email if interested or if you have a pair that is collecting dust. The original HF-20's never sounded very good at all. Once I ditch that Williamson circuit and put in what I like to use it's night and day. What a HUGE improvement. It’s amazing they even ever used that Williamson circuit, so dull, flat and boring.
red post is 8 ohm white is 16 ohm.

Dyna ST-70 Rebuild
Dyna ST-70 Rebuild
One of my favorite rebuilds yet.. Man this Gal can sing. Those huge UL output transformers. Upgraded power transformer, NO CIRCUIT BOARDS. NO ADJUSTING BIAS. Just the famous JWN circuit and some fabulous iron.
If you have an ST70 that just doesn’t cut it send it over to my shop. Bet it will blow you away when done.. Asking $550 for a complete rebuild of ST70, new power transformer, dual power supply feeds, one for signal tubes and one for power tubes, allows use of many substitutions of rectifier tubes and power tunes. If interested email me and we can chat a bit more. Way too much to describe here..

Bye, bye flimsy printed circuit board.. Hello good old point to point with careful attention to each solder joint. All new resistors and caps. Get that old ST70 that’s collecting dust up and singing again, a piece of history, audio art if you will...
any combination of dual triode tubes can be used. Select what you like.

Another massive PPP 6L6 unit, huge iron, huge sound, big power. This one is a bit more compact then the previous PPP 6L6 units.
Amplifier uses 4-6L6 or EL34 power tubes per channel. Approx 75w a side. Runs cool and quiet. Check out the pics. Separate fil trans is used to keep the load off the power trans and chokes are used in both b+ feeds, one for the power tubes one for the smaller 6SN7 tubes. Rock solid and stable. You simply will not find another one of these. Plug in and play, thats it.

6CG7 input and phase inverter tubes are used, 5U4Gb rectifiers. Any good 6L6, 5881 or EL34 tubes may be used with excellent results. Larger 6550 tubes will not safely fit. Sounds amazing, got to love that UL mode, so smooth, powerful and dynamic. Old Baldwin organ amp chassis, getting harder and harder to find for a decent price today. This one is totally rebuilt, new everything except for the chassis and some tube sockets.
If you like, contact with questions or custom builds or rebuilds.

Basic power amplifier, vintage transformers, massive power, great punchy sound. Owner is very pleased, useing 2 ohm infinity speakers!!, his fancy chrome Chinese amp is now a paper weight. don't let the 40 watt jukebox output transformers fool you with their size.. The power and tone of this amp are mind boggling.
Uses 6SN7 input and inverter tubes and set of 5R4 rectifiers, plate voltage is near 500v. Individual cathode bias is used, no adjustments, just like with all my units, throw in some good tubes, plug it in, sit back and listen, period.

built on an old Hammond organ amp chassis using Baldwin output trannies.
talk about going green,, constantly recycling over here, nothing like using good vintage parts, hell, even recycle vintage wire in my units, so long as its in good shape of course.
This one also has individual bias and huge power plant. El34,6L6GC,KT66,KT77 tubes all may be substituted to liking.

 SOLD... 
To an extremely satisfied gentleman who has had every Mc30, 60, 275.. go figure..
The latest and greatest.. Cranked this one out last month,(4/10) Added finishing touches this month (5/10).  Huge,  Industrial, massive, powerful and quiet. Push Pull Parallel amplifier. A serious unit that gets the job done plus some..  Approx 60 watt per channel with 6L6 and 70w or so with EL34 power tubes. 351v on the plates is nice and easy on the power tubes and sounds so sweet and deep. Tubes will last a lifetime in this unit. Huge transformers and a massive choke let this baby run long and cool. Dual 5U4GB rectifiers are used to feed the B+ to the power tubes.  The trio of 12AU7 signal tubes have their own supply fed from a separate winding and set of diodes and chokes. A perfect unit for those with power hungry speakers, nothing like having four 6L6 for each channel. Check out the close ups of the trannies. Brazillian cherry hardwood trim, gold and black paint, smaller choke is a grey tone. Please feel free to contact me with questions.

the toggle switch is three position.
towards rear is all on
middle is all off
towards front is standby mode, only the fil trans gets power and keeps tubes warm. The big red pilot lamp in between the rectifiers lets you know when power is flowing. Amp was built from an old organ amp with tons of holes in odd places, did my best to fill and cover them up.

Here's what owner says...

Hello Jim:
Pretty awesome amp!!!-- I tried it with an Ipod direct and with a mixer as pre-amp and I have listened for about 4 hours straight-all I can say is WOW- Dead clean music- The way it should be. - It does everything and then some-- Also the transformers are barely warm- I can listen at low level volume and still get all the sound-- works great with the Pioneer HPM 100 speakers-- (But I am still looking for some Klipsch horns or Cornwalls and maybe Heresys)-- Hard to find here in the midwest".

Huge chassis, huge iron, huge sound. Approx. 65 watt a side. Dual 5U4 rectifiers power the output tubes, input tubes are fed from separate winding via a set of diodes. 6SN7 tubes are used for the input and inverter drivers. Huge beer can sized caps were used in the power supply, check out the close ups of the transformers, monsters.. Weighs an easy 70 lbs
Perfect for power hungry speakers, output impedance is 8 ohm, 4 ohm is no problem. A real power house, grave yard quiet too.. Monster of an amp..
Asking $950.

Midnight.. Black paint job and ebony stained poplar wood trim. Good for 30 watts per channel. 807 tubes loaf at 390vdc on the plates. Dual 5R4GY rectifier tubes and 12AU7 type inverter drivers are used. 6SN7 input stage drives each channel. Vintage chassis and transformers are used, as usual. 4, 8, and 16 ohm taps are avail on the robust output transformers. Heavy duty speaker binding posts and gold rca input jacks are used. Silent operation, no noise or hum , period. Built with oversized caps and resistors, will last a lifetime, so long as a proper strong quad of 807 tubes are used. Power supply is more than ample, huge power trans, huge caps and choke filter are used, dc is clean and quiet..
