Disipation on sit is a lot, 25V x 4A = 100watt, and power supply of 65Vdc and 4A, 260watt. So, 160watt on resistor..... I can not touch more of 2 or 3 seconds.

I have been listening this "little amp" during two weeks. It is wonderful.
With AERMK1, voices are spectaculars, instruments separation, definition. There is one passage in Wagner's ring with three vocals very similars. It is possible follow each without problem. I never have listening this before.
Two pianos simultaneous are simply spectacular, very complex melodies are recognizable. What can I say more?

Jama,
my congratulations! Your enthusiastic sound description reads a little like a spectacular tube amp description. Great!
Hope to get to see some details regarding your schematic?
I'm meanwhile matching my 2SK82's (based on the Frankenstein hint) to get my hybrid amp going.
Best regards from Braunschweig,
Ulrich

Thank you Esteban and Ulrich. Again, merit is not mine. I only got some components and join.... Schematic is the same that lamp of Michael. Only I did a little change, I used choke grid instead of 47K for bias and, of course, THF-51S. The next step will be mount the second channel and listen again.

Super DIY
Thank all. It is an honor so many important people says nice words about me. Thanks a million....
Well, today I am comparing two versions, one channel bulbs and other with resistor. To be honest, I can not hear musical difference between both channels. But, version with resistor is more silent. But because all aluminiun is connect to ground and trafo is away from signals.

@ Michael and Diyers
Step by step i try in near future how curves looks from new batch
of Tokin 182ES | 180 "candles" but for today simple tests
with 8R2 power resistor and small 1K.
Ok i must finish psu for my tracer ....stay in tune
Have a nice day
