Although what you say is true about the need to recap virtually any electronics where the electrolytic, fluid filled capacitors are more than 20 years old, the fact is I've never heard of any serious SE/30 problem that pertains to the analog board or PSU because of leaky/aging caps on them. In almost every case of problems with an SE/30, it usually goes back to bad caps on the logic board. Of course, in the case being discussed in this particular thread, the circumstances are a bit extraordinary — it looks like the user may have shorted something and destroyed components. Therefore, the problem most likely lies on the analog board, and it's doubtful that problem has anything to do with aging caps on it.
