Hi Steve
Last night after reading your post I checked the back of the amps. Since I still have one old and one new amp I touched the back of both. The old amp was cool to the touch and the new one was hot. I will be phoning Axiom today to find out what I should do since I wanted to change out my other amp this weekend \:\(
Sorry to hear about your misfortune but thanks again for giving the rest of us the heads up about this.
