Capacitor for old The Fisher Amp, what can I replace it with without hurting sound, can't find cross over, numbers on this one 2000mfd, 55 w.v. c50 180-102, 820-68. This is not a tube amp. I found numbers close but I don't know much about effects it will have not using exact same. Any help would be great Thanks Jim

 

Any electrolytic cap with equal or higher ratings (\(\geq\)2000μF, \(\geq\)55VDC) that will fit should work fine. It's likely just a filter capacitor and its value is non critical to the sound.

 

Looks like someone replaced one next to it, canister ground was not used, just two internal hook ups, smaller blue one newer style. Jim
