Hello, first post here. Hoping to find some answers. I am having an issue with an SX-1010 power supply and not sure where I am going wrong. Perhaps someone could help me. This unit had a fried resistor, I believe it was R12. The PCB was damaged so we built a new one and put the components back on. With the board disconnected except for pins 1-2-3-4 and 5, referencing pin 7 as ground, we get the following voltages:
Pin6 = 6.5 VDC
Pin7 - Ground
Pin8 = 2.2 VDC
Pin9 = -76 VDC (-9VDC)
Pin10 = -76 VDC (-56VDC)
Pin11 = -76VDC (-24VDC)
Pin12 = Ground
Pin13 = 2 VDC (35VDC)
Pin14 = 3 VDC (56VDC)
Pin15 = 3 VDC (24VDC)

I have uploaded a link to a service manual here. I know there is a couple of gurus on here so I am hoping they can help me figure this out. Let me know what I need to do.
