It's easy to armchair quarterback something when you already know the outcome. I started from a perspective of being told that the amp had just been given the green light from a tech. My buddy thought he smelled something which standing right there seemed to be coming from the other side of the amp- glue and old foam (very volatile stuff) stuck to the heat sink and producing an odor at normal operating temp (assuming the thermostats were working to spec). He said the fan came on and shut off like he would expect. So I thought it was a case of overabundance of caution. Turns out the failure that occurred likely didn't have anything to do with the smell that he was worried about. It's become apparent that I could have made myself look better by including the full story in my original post. Or Shadowgroover could have asked where my head was at when this was going on. Instead he pointed fingers, called my actions pathetic, and called me a foolish perpetrator. He also made it clear that he thinks I deserve to have the amp blow up on me. You commend him. Bless both you guys.
