You have a bunch of goodies on the top deck, How about a peek under the copper. Looks great. How is the sound? Is it playing yet or still on the bench?

Briney, those transformers look very expensive but very nice.

No sir! James is a true audio bargain. If those are 6123HS (5K 20 watt) Euphonia Audio's current price is $205 USD/pair.

The James are from Euphonia. They are much much better the Hammonds. The best part is the opts were a christmas present from
the wife!!

Single ended pure class A, experimented 2 years ago. 50W output, 200W consumption, brilliant sound, flat from 10 Hz to 200 KHz. You may see a white blower from microwave beneath the heatsink, once I forgot to switch it on and got output FET unsoldered... 😉
A tube is from TV, Compactron with a high mu triode inside and a power pentode, I connected it as a triode.

Horn loaded isobaric subwoofer, will be finished soon. I am going to check it ower the entire frequency band before covering by memory-foam and a leather imitation vinyl for some remained resonances and air leakages..
Line array stereo speakers, 300W nominal each, wide horisontal dispersion, 50-22000 Hz. I use them from 80 Hz because despite of careful damping and hardening of long surfaces they are very long anyway...
Guitar power amp with solid state regulators, made about 2 years ago for home studio recordings, 2x 6L6G and 6N1P
Back it up mister...
You gotta tell us what the @#$% is goin down with post 1271 ????
Nice work man! Rock on!

Re: Back it up mister...
Thanks man!
The thumb stays in the garage waiting for the really cold winter. 😀
About a kilowatt of a heat for 2x100W of output power is too much for a summer time...

And I am busy with this one now, I need something good with 500W of continuous sinusoidal output power on 2 Ohms to power my new subwoofer.

Re: Re: Re: Back it up mister...
Nothing special inside, just a power supply to generate heat, plus some 8 NPN transistors to make temperature independent of sound volume, plus some 8 FET repeaters to heat the heatsink more, and couple of double triodes with really red hot cathodes and filaments. Also, it has couple of magic eyes, since it replaces a fireplace it need to have something to look at... 🙄
