Your OITPC is unknown to me so it's up to you to provide Thimios a cap/resistor combo to increase the PM/GM for testing.
I'm out.

Let's see how this measured when not oscillate.
Distortion value is close enough to my sound card loop THD.

I haven't sometimes not oscillate.
Just now i try using +/-35v and up to now i can, :see any oscillation.....but now i use input signal from a function generator.
Still +/-15 is ok.

I think so too!
Sinusoidal test.
The 47pf is under the board🙂
There also, 1nf from base to gnd at the cascode but i will try to remove as no improvement when testing using +/-50v

FFT analyze
+/-35v
idle=130mA
First 1,2,2,4 the sound card loop test.

Thanks Damir for this excellent amplifier.
Bravo!
Please feel free to ask any other measurement-test. 🙂
P.S let me to say thanks to a very good friend from Belgium, who donate me the Laterals.
Thanks xxxx🙂

What about listening test, I think you said you don't have good enough loudspeakers?
Unfortunately not... and i have one chanel only, up to now.
This was my last piece of duble side photoresist pcb🙁
Listening to one chanel isn't a good practice but those measurements say all the story about what expected. 😎

I manage to run this at +/-35v and everything is under control.
May be Damir will find the way to be stable at +/-50v latter. 😉
