Thanks a bunch Morris. Yes, that helps! I figured it had to be one of those two transistors, but while they are easy to remove/replace physically, I was trying to find where the EBC leads wound up on the ceramic strip so I could take some measurements, but their sockets and V193 are completely covered by the parts on the ceramic strips. I can't even see them. I wasn't having much luck trying to figure out which parts on the strips matched the schematic. That is why I asked if there was some kind of parts placement diagram someplace.
