McIntosh MAC 1900/PSB 5T burning smell

Hi-
I recently bought a MAC 1900 from someone on ebay with 100% positive feedback (I mention that only because I have to assume the seller wasn't selling me snake oil). It was well packed but I'm sure it was turned on it's side and/or upside down a number of times. I hooked it up to a pair of PSB Image 5T's and within 10-15 min it smelled like something was burning. I felt around the surface and everything was cold (too cold). So I let it sit until it got to room temperature and tried a again. Within 5 minutes, smelled like burning again. This may be completely unrelated, but the high's began to sound a bit muddled as well. I've started an insurance claim with FedEx and depending on the outcome, I'm planning on having it repaired if I'm able to keep it..but any thought/advice on this issue?

@j_stereo This is very helpful. I'll buy a multimeter tonight and do that. What range of output would be acceptable?

Eli - anything greater than Millivolts is too much, but you shouldn't even have to go that far because if there is any smell of heat or burning there is something wrong with the receiver. When these receivers are in proper working order they don't generate any substantial heat even when driven hard, and they definitely should not be generating any smell. I am guessing there is something wrong with the receiver to make these components get hot, and it probably should not be used until the problem is resolved or it may damage your speakers.

@j_stereo Thank you again for the help. I was trying to work around bringing it in because I was excited to get it and use it..but I think I need to bite the bullet..Especially with the potential for a house fire.
