musical fidelity a3.2 blown left channel, repair?


I was out of town a few weeks ago and returned home to find that my roommates managed to blow the right channel of my musical fidelity a3.2, in addition to the woofers on a pair of B&W DM302s. I don't know exactly what's wrong with the amp� but I'd be curious to see what some hypotheses are and if anyone has a good repair recommendation in NYC. I tried using a variety of cables/speakers and nothing could bring the left side back to life; the right side is still pumping out sound, presumably because the amp is dual mono. Still, I'm ignorant of what's actually going on and welcome advice/comments. Hopefully it's just a blown fuse or something, but if not, I'll be in the market for a new integrated amp.

The voice coils probably overheated and started chaffing and eventually arced to ground this probably overheated and blew the output transistor(s) in one channel on your amp. You should get the amp repaired - the speakers will need new drivers but you might as well get new speakers as it won't be worth the cost to repair them.
MF's repair is in Charlotte, NC last I heard. I know the person doing it and he has been in audio about 30 years and is very competent.
You know your roomies ( and their friends) -if you think they blew 'em - they should be up for the cost of repairs.
Disconnect amp from power and speakers - remove covers - if you know what a fuse looks like -look for a blown one in one channel- these can be a anywhere - but back panel,top of PC board or bottom of PCB are most likely locations.Most stereo amps are symmetrical - look at the working channel and then look at what is different about the non-working channel -anything scorched/burned or bulged in the dead channel that looks better in the working channel is suspect.If you ( or the roomies) have led exemplary lives - maybe it'll be a fuse?
Don't assume the speaker is blown until you've had it tested.
