Everyone thanks for the suggestions! I have 7 more resistors to replace and then I will have replaced all resistors. I will replace those in the next week or two and then the socket on that channel. The thing that gets me is that I have already replaced all resistors that exist in pairs. I would have thought that with one channel having the issue that the damaged component would have been a component that existed in a pair. This leads me to believe it is in the socket, though there are also two relays. Oh well in the end I will replace everything, and I am sure the very last thing I replace will be the component with the issue. Yeah I was also kinda worried about the whole premadonna engineer issue, that will not fly with me, I am also an engineer, but I am a plant electrical engineer, not small circuit stuff, 480 at lots of amps, big motors encoders, solenoids, starters, relays and such. To me components meet/exceed spec or don't, I don't have much time for whiny engineers, I deal with enough of them professionally.
Please keep any suggestions coming and thanks again!
