I have a B 2x. it gets hot on the left side hotter than the right side still plays real good equal volume seems on both sides but you can barely lay your hand on one side of it what might be wrong with it

I have owned the YAMAHA B2-X for over twenty years. I have been very happy to have it as my main amp running MAGNEPAN TYMPANI 4 AND MG3.3 speakers. These speakers are very hard to drive. i have owned the YAMAHA b-2, M-2,M80,M85 amps. None of these hold a candle to the B2X. A true dual mono amp with amazing detail. I consider it very close to the YAMAHA B-1 in sound. i should know as i owned one of these for fifteen years! Ionly sold the B-1 BECAUSE IT CANNOT BE FIXED.the b2x can. For a 1985 amp to retail for 1500, it was a great deal then and a better deal now. IT WAS THE ONLY AMP TO BRING OUT THE TIGHT BASS IN A MAGNEPAN I HAVE USED.I HAVE OWNED S.A.E,PHILIPS MADE BY MAC,BIG DENONS AND OTHERS. Forget the light shows and get this amp!
