I'm gonna try to check all those solder joints while I think about the problem too! A lot of electrolyte did scatter so hopefully I'll find something eaten up on the board. I already replaced all capacitors on the board. We'll see!The times I've found those while going over the soldering as something to do while I think about the problem.............
Very often the escaping electrolyte eats through one of the capacitor's legs, these also show up as no longer attached to anything while re-working the solder joints.
