Thimios, thank you for the observation - this mistake has come back again.
It's connected the right way in the layout though.
I will correct it again. It has to go to the amplifier's input pair.
Crap - connection in the layout is also wrong The good one is only in my workshop-manufactured boards.
OK, last correction - tomorrow.
Thimios, your 20khz clip waveform* is exactly what I am getting with Lichtstark. I was thinking it may be a problem with my build.
* notch showing coming out of clip (+) and going into clip (-)
Post#80
I am getting 72v p-p from 40v (no load) rails @ 8 ohms. VAS regulated at +- 44v
Lichtstark is an excellent sounding amp.

Huh! Yes, this OPS file is also based on that early version of the schematic.
The drawback of maintaining the design files on 2 PCs
At least it doesn't affect the layout.
Scrubbing my eyes: What's the bug with Q10?
Best regards!
The part value is incorrect, should be an IRF240, copy and paste error while drawing the schematic.

It has to be marked as IRFP240. Typo mistake
Well, I've seen the IRF240 denominator before posting #106?
Best regards!
Yes, it was corrected, but then the mistake came back again as I used the wrong version of the schematic for OPS.
