I have replaced R89 + R88 and R89 as those fusible resistors were open too. All the remaining fusible resistors check ok. The amp is now humming very loudly when powered on and plugged into a speaker and reads 35VDC across the speaker output wires.
Q11 now reads to ground with the amp powered on:
E: ~+40VDC C: -42VDC B: ~+40VDC
so based on an earlier post I would assume Q11 is the likely culprit? I think Q11 should be C: +42VDC
