The 2 pin violet connector is from the 100VAC winding - used to make the -113 and -125

The white wires make the 80 VAC winding, converted to 62 volts, come from the rectangular plug in the cabinet. Pins 5&8

I'd be very surprised if this is anything but a HV problem.

My suggestion - don't just replace 1 component, shotgun it.

I don't normally suggest shotgunning any repairs, but HV problems are the exception. The enemy here is heat. Everything on the board has been exposed to heat. If you replace 1 resistor or diode, you'll be in there replacing another one tomorrow.
