I've found instances of regulation failures caused by loose hardware. In particular the nuts atop the filter caps that hold the regulator PC board loosen and simply tightening then will cure the issue. This appears to be caused by compression of the PC board material …"cold flow" to some readers.
There are several other common failures of this series of PS's, but this one is perhaps the most prevalent. While you have the cover off, check for paint under the lug on the green power cord wire … 73!
