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

better safe than sorry. I was fortunate that the only authorized KRELL service centre in Canada is only 2 hours away. Units are in for tuneup/checkup servicing. I will post outcome.
Guess what ? The one monoblock had been tampered with and had output transistors replaced with inferior ones. Cost to fix $450 US. Items were bought on audiogon - seller is suspended and is no longer contactable by original address nor phone - not sure what possible recourse I have. Moderator ?
