Hi everyone,
I had a Sunfire True Subwoofer which was making a buzzing noise when it when it was on with no signal. It made more of a buzzing noise when it had a signal.
I figure it was bad caps in the power supply so I replaced all the electrolytic caps. This fixed the problem and there no noise at all, so I'm very happy with the result.
I used both a multimeter and a multi-function tester to check the old capacitors. However all of them measure well within spec.
The caps I replaced were
2 x 1500uf 200v
4 x 1000uf 25v
They all measured well within 10%, but at least one of them must be faulty. How can I find out which one is faulty?
