There is one individual on this board who is someone familiar with the EE principles and has the schematics for the SE/30 and probably could zero down on the culprit(s) fairly quickly. I'm sure he can find this thread if the time is right for him, he's overloaded right now.

Given the rate of death on these machines, it's in your interest to try to repair the board, if it is feasible. Any good board without capacitor or battery damage that just has a minor issue should be a candidate for repair.
