Very linear tubes....of course.....6S33S.
Pretubes are russian amazing 6E5P. Two power CLCRC channels. I built it this spring.
Sorry....I have a mistake for post the pfoto.
I'll try later....

very nice work there..what sort of specs does that amp have? Importantly, how are you liking the sound?

 

[azazello]

Freq. band is more 25-30000 Hz, Input signal about 150 mv. Outputs for speakers - 8 ohms. Output power about 12watts.
Amp consist 2 stages!
Ra = 1200 ohms, alpha about 6. Iron - 25 sq. cm, Ua = 210v, -U=72 v. Ia=270 ma. Ua6E5P=162v, Ia=30ma.
All caps are Nichikon, cathode shunts - Black Gate, rect. diods - BYV26E.
No hmmm in my 96 db Fostex206E in hornes. The sound is.....something like good for me..../Sorry for my bad English....!/.

v nice casework.

Very nice work!  Did you develop the circuit yourself or are there schematics out there?

This is russian standart schematic, but modes of 6S33S and 6E5P are according some my listening and decisions and possibility of PSU.
I didn't like sound with Ua-c=180v, but with Uc-a=220v the sound was agressive. Output transformer was made under advices of Russian and my friend tube Guru A.Manakov /thanks Anatoli!/. All stuff of PSU is my decision with my calculations.
