Glen, it could be a bad cap on the -10V as the voltage is lower than it should be and of all the caps, that is where I see 4.6V of AC.? I'm going to take it out and bridge in a cap that I have in that range.? It strange that it is showing up in the 12V supply but I guess since the reference voltage is hosed it could be the issue.
It's almost always a cap.
Thanks
Jerry
