"pin 4 is 95 DC. Pin 5 is the same @ 95 DC and 10.7 AC"
Is this left channel or right channel or are they both the same?
The heater doesn't need to share a ground with B+ which may explain some of these voltages. I just looked at the original PAS3 manual and it shows pin 9 (heater center taps) on PC6 is connected to B+ ground. Is this connected on your PAS? It is shown on the schematic above, it is on the bottom of this attached schematic, right before the "eyelet" notations. If it isn't connected, I would connect it and try it, and it should correct the pin 4 and 5 DCV to chassis/B+ ground.
