I have an Infinity BU-120 powered subwoofer which quit working. Removing the connection panel (which carries the circuit board) revealed that one of the electrolyic capacitors had self-destructed. Circuit designation is C6, but there is no indication of which connection is positive or negative. I was told that the spec value of that capacitor C6 was undervalued, and to replace it with a 10mfd/250VDC. No indication of polarity. Any help would be greatly appreciated.

As an aside, the 3A slo-blo fuse was open.

My son has the same unit, with the same problem. I have both circuits here, and am trying to get my son\'s fixed, at least, so he can have it. Mine can wait.

Thanks!
