So this is a stupid question. A friend messed up the input jack on his Peavey solid-state amp, so I'm going to replace it. It's loaded up with a dozen electrolytic caps, so I figure I'll replace those while I'm in there as well - they're probably 10 years old at this point. A bunch of them are glued, presumably to prevent vibration issues. So probably I should glue the replacements as well.
My question is, what kind of glue should I be use after replacing the old caps?
I use GE Silicone II clear, you can get it at Home Depot & just about everywhere. It is a different formula than GE Silicone I, which is the acetic acid generating formula, you do NOT want that.
GE Silicone II generates ammonia, ie is an alkaline cure, not an acidic cure.
I would test those small electrolytics before you change them out, if they test OK don't change 'em out. I just finished servicing a 1960 Fender Super that had an all original board population including all electrolytics, and even the bias board caps were still OK, dated 60-04!. I have an LCR meter that can accurately check caps in situ. (I did change out the entire main power supply caps though).
