Thank you Guys ! 🙂
Oh, I let expert idiophile members daanve, Dimitris AR, mbrennwa, nicoch58, Schmitz77
the leisure to guess, comment and describe my supposed circuit with their jealousy, uglyness and denigration, in the absence of their knowledge... 😀
A+!

Thanks @azazello ! 🙂
That said, due to extreme compacity (275 x 175 x 65mm for one chassis), there's a 3-speed fan cooling at the back, using a chimney effect around the 6080 :
Fortunately, the 1st speed is enough to maintain the chassis cold and limit the heat around the 6080 at a reasonable value... 😎
The power output is 10WRMS on 16R, the onset of clipping being at 13-14WRMS. The bandwith is less than 1Hz to 250KHz. THD is circa 1.5 to 2% H2 at 10W.
A+!
Thanks @jim ! 🙂
Yes, I find them very practical, reliable and cost effective. Another great point of interest to me is that it allow the building of compact amps. I used these ones :
Hammond 1550J :: Diecast Aluminum :: Enclosures Boxes :: Electronic Parts :: Banzai Music GmbH
Parts placement :
Tracing and drilling :
Engine turning :
Pre-assembly :
A+!
Very nice amp congrats, I have a question, what would be the outcome of a failure on one tube to the speaker ? ...all the best
Tubelectron , you have a very bad character , I hope the amp " sounds " much better than you ! .

Thanks @kissabout2002 !🙂
Nearly nothing on a true OTL SEPP circuit - and by the way nothing dangerous for a speaker : at worse of the worse, 0.5 to 1VDC offset voltage, that can be easily identified. Remember that 1WRMS on 8R represents 2.83V...
A+!
Not in speaker output on mine, but on the plate voltage going to the 6080 - see the faceplates below (+115V and -115V fuses) :
A+!
This isn't mine but this is stunning.
I can see how this could be made in a DIY form - a walnut cutting block, a metal inside shielding, a metal plate on top to provide a convection guide and heatsink.

Yup. This VR is on the bias supply.
EDIT: Also, I can't see it like this with my naked eye.
