Motor boating

I have a Companion 3 series II Bose computer sound system that is motor boating through the speakers at idle that drives me crazy. My experience says it's probably a bad capacitor on the B+ side of the power circuit. I have the circuit board out and I see a 25V 33000uf  can. Is this a common problem? Are parts available? I would like to fix this and not have to trash it.
