Just a reply to myself. STacy issue was interesting. Apparently cap juice had wicked up the 5v POT. I recapped it a while ago, but didn't catch that. That is what was causing the 5v instability. I was looking for other parts dragging down the power supply, isolating various things like the motherboard, the PSU, etc etc. But since the problem was intermittent it was a little tough to catch. Reggie had a spare 10ohm potentiometer, went to solder it in. Immediately got that fish smell and found some of the solder "crunchy." Replaced that potentiometer -- rock solid power. Sometimes the obvious thing is the actual issue.
