Checked the output section on this, No extra shorted pins on the output
ICs, closed the relay in the power supply and had + and - 66VDC going
to the output ICs, there is a regulatour STK470-050 also in the power
supply. I have no idea what this should put out on what pins and cables
are too short to run unit without completely reassembling it.
Would someone have a copy of the schematic available for the power
supply and control circuit on this?
Thanks
