I checked the outputs and Amp boards visually and did a quick check on the Drivers and transistors. Every thing checked good on both Amplifier boards and heatsinks.
Checking all the fuses; all checked good.
No blow-outs on any boards.
Pluged it in, Had the High Res print of the Power Supply schematic in front of me. DMM set to DC volts. Grounded to chassis. Flipped the power switch on. And:
Pins: (Should be)
13 = zero volts (13.5v)
14 = zero volts (13.5v)
16 = zero volts (8v)
15 = zero volts (5v)
17 = -3.4 (80v)
9 = -8.5 (34v)
12 = -8.5 (30v)
8 = -30 (-30v)
9 = -35.2 (-34v)
12 = -0 (-80v)
The set is original except for some work on the Power Supply board. New paste, looks like older parts and original caps are still installed.
