All of the symptoms you describe are the sort that are frequently caused by
leaky caps. Any time I hear thumping on a gate or VCA, my first thought
is there is DC someplace where there shouldn't be.

Don't worry about the pins being bent over. Cut off the capacitors on the
board side, then the desoldering tool will just remove the pin residue
quickly and completely leaving a nice clean hole.

Why did you remove the capacitors to do an ESR test? The whole point of
the ESR tester is that you can do rough quality checks in-circuit. Once
it's removed, you might as well just replace it anyway rather than trying
to salvage the original part.
