Hi I have a problem with my subwoofer humming only connected to the mains nothing else. Ive had a look at it and taken some pics. Can anyone tell me please if the CAPS have blown from these pics?

Next question can anyone replace them for me obviously happy to pay for the work I cant solder.

They don't look too bad but they may have dried out and thus lost some capacitance.

The big one looks like it has a date on it (looks like 14/4/15) and so they might be nearing their change out time as 8-10 years is considered normal for caps used in power supplies and filters... but this depends a lot of the operating conditions.

If you get stuck I could swap them out for you but we live at opposite ends of the southwest, so that kind gets in the way.

Just had a quick look to see if there's any small scale repairers in Plymouth and found this guy, might be worth a try.

Thanks much appreciated its about 16 years old I think so quite old but its sounds amazing Id have ro spend near 800 to get the sound quality today. It works but hums after a while ill see if replacing the caps works as its a cheap fix and others have tried it and it worked for them. If not ill have to fork out I guess.
