I have a Sunn concert bass amp that probably needs some repair. It will play fine for a while, then the volume will dip before swelling back really loud. Does this sound like a capacitor or power supply issue? The other possibility I have considered is whether the cab I have been using is wired incorrectly and not providing adequate ohmage, but that seems less likely.

I'm hoping getting it serviced and recapped will fix the issue. Any repair recommendations in Los Angeles?
