Wow, thanks a lot Mr. Pass I greatly appreciate you took those tests, it's really generous from you!
I didn't want to bother you with this issue just beeing curious how such a GND layout doesn't cause any major hum.
It's intresting what the simulated model was missing if the real life measurements are so different.
Thanks anyway!

Hah! That's wonderful.

Thank you Papa for the measurements.

Please see the last post in the thread "Compound power amplifiers'. It shows the schematic of a powerful power amp which embodies positive current feedback.
