Got this sub basically for free from a guy a bought some surround sound speakers off. It's a proper beast of a sub and sounds amazing.
Its basically got a loud hum when powered on, a little hum in standby but mainly when powered on.
Cracked it open and all Jun Fu caps and from what I've gathered from here is they last just about as long as the warranty does. Given sub is about 6 years old I suspect its the caps. Normally I would just cheap out and just replace caps that need replacing but I think this is worth a full recap and to be fair there aren't that many electrolytics in it.
Don't want to change the main caps if I don't have to as they are expensive? if not will replace too. Anyhow these are the caps
Jun Fu - 100uf 100v (HK105 0501)
3 x Jun Fu - 220uf 25v (RB 0411)
7 x Jun Fu - 100uf 16v (RB 0502)
4 x Jun Fu - 22uf 25v (LL)
Jun Fu - 2.2uf 50v (LL)
Main Caps
2 x Jun Fu - 4700uf 80v (LP 0501)
Questions, will Panasonic FCs be suitable to replace these or do I need audio grade stuff? Or anything better.
If I was to replace main caps what caps should I use, are the main caps just regular caps or are filter caps a different type?
