Okay just to be clear.... At the moment I have one leg lifted on the lift the 270 ohm resistor, all 3 muting transistors out, the trace cut in multiple spots with no jumper wire in place.

Do you still want me to lift the end of the 100k that's not connected to the diode and check voltage? And if so, check it where?

Check the voltage on the leg you desolder.

We are back to square 1. If you have -20v on the desoldered leg of the 100k, check for DC voltage leakage on the board.

Just wondering if you eventually figured out what the issue was with this amp?
