Yes, I have isolated the problem to the Amp, I think. Here is a symptom that I am hoping will lead some of you toward solving this problem.
After I cleaned the contacts, I plugged in the amp to the power, and it would turn on and off. Then I attached the left speaker, and I could still turn it on and off. Then, I attached the right speaker, and boom here comes the static. And when the static noise is occurring, the amp will not power up. The switch does not catch when depressed.
I had the top of the amp off, and decided to monkey with the fuse to see what would happen. I unscrewed the top of the spring-loaded fuse holder, and the sound went off, and a red light lit up on the circuit board near the fuse. Then I re-engaged the fuse by screwing in the top of the fuseholder again, and the noise was gone!
I decided that this was strange, but that I would just keep the screws out of the lid to the amp so I could do this if I had to. I ran the amp for several hours with no problem, then turned off the power supply, effectively unplugging it from the wall. When I turned the power supply on again, there was the static. So I repeated my fuse trick and voila, no static. After playing for 10 minutes, the static returned, and I powered down the system.
Does this help in the diagnosis department?
Thanks,
Greg
