im going to recap my subs plate amp.

I have a quiet hum and usually I cant hear it but at the times I can is annoying. its not ground loop. I tested circuitry ground with a specific tested. ground is good. hum is even when no rca is connected in from AVR. different power outlet. all the same. I got the sub and its in mint condition, I think its quite an old sub.

looking for an online store that INTL ship high quality caps and where are good caps made?

japan, eu, usa?
