As I mentioned, I also received a Peavey amp for repair.
Same problem, except this time some of the values were different.
Two of them are 47uF 500 VW, another is 22uF @ 450 VW, and two of the already known 22uF @ 500 VW. The 47 uF were so aggresivly glued to the circuit board, the only way to remove them was to slit the plastic outer insulation, remove the aluminium can, then cut the outer plastic sleeve off in many small pieces. The glue is so strong I ripped one lead out of the end plug trying to remove the cap. It was glued BY THE LEAD ONLY!!!!!
about one hour to remove the caps.
After having seen these fail I would suggest that anybody working on an American made amp that works fairly hard, to replace these on sight.
BUT I have measured all the low voltage caps ( there's big mobs of sand caterpillars for pre amps, reverb drive and recovery) and they are still all perfectly good.
