Re: strange electrical issue - anyone have any knowledge of what to do.
I have to wonder if the Pyramid power supplies that have failed in the past couple of years that we have heard about so far, are specifically because of this vibration-caused, failed cap issue.
It is the type of delayed-failure that would not be detected by routine assembly-line QC testing.
It might be interesting if people who owned these power supplies would all open the cases and look for the potting compound around their caps and note the approximate date when they received their power supplies.

I noticed that too but wasn’t sure what it was. I just re-read the original post and this is the good working board. So looking visually wouldn’t have done anything anyway.
But I did learn something today…I’ll mark the calander……if I can find it….
That is definitely a hard potting compound and
not leakage from the caps.
