Why would 1 SS monoblock run hotter than other?


amps in question are KRELL KMA-100's '88 vintage.
I've switched amps from side to side but 1 always run significantly hotter( very warm to touch whereas other is cool ).

Need I be worried ? or should I not touch it til it breaks ?

thanks everyone

I would guess bias current is off in the cooler running amp and the amps won't sound the same under these conditions. You should contact Krell and see if they will tell you how to make this adjustment or someone to service it locally. There are normally trim pots to adjust but you need to know where to measure and what the current should be.
