Tripping Breakers

I have a musical fidelity KW500 that trips a 20 amp (dedicated curcuit/12 gauge wire/hospital receptacle) the instant the power switch is pushed. I have checked everything I can think of that could cause it (hookup is fine). Everything else about the system and circuit is unchanged and has worked for years. When it did turn on before it sounded great and played without tripping the breaker. Anybody else have this problem? If so what was it? Your help is appreciated. Chris.

Sounds like the KW500 has a short and fairly large fuses?
Sometimes you can see or smell what is fried by popping the cover off (after ac power disconnected and caps are discharged!) and giving everything a good look see. Other thing, if it is tripping a GFCI breaker you might just be looking for a slight short to ground, sometimes you can get resistance to ground back up to snuff by just blowing clean with an instrument air bottle (radio shack) and wiping away obvious dust.
