Let me guess: Blown power supply in a 7704a or similar? Enjoy finding the root cause, maybe in a similar fashion as this person...

Yep. It's a 7904 with the dreaded ticking disease. I didn't get as far into troubleshooting it as I hoped this weekend, but I now think the trouble is in the mainframe, and not in the power supply.

Unfortunately, I need to move on to other projects this week, and I don't know when I'll be able to get back to it...
