R75/76 it can blow open under your heavy prior abuse. It will not show any signs of overwattage, just goes open...

Not gonna be that easy, R35 is now 7.24K ohms....

R35 replaced witha 1 ohm 1/4 warr MO. Left channel R35 also out of spec, it was reading 10.5 ohms. Bias now holding 385mv. Back on the AP....

Looks like those 1 ohm fuses did their job. Now that you have the wire relocated from the backplane, that should not occur again.
