There probably is a "run capacitor" on your a/c compressor. As pointed out in other replies, it is a sign that you might need a service call. If the fault only occurs when the a/c compressor starts and runs, then the trouble shooting should be easy. Good luck. BTW, this should be a simple service call, perhaps, and I STRESS perhaps, you might be looking at a compressor, but I would get a second opinion for anything over a couple hundred$$$
Short?
I have a McIntosh integrated hybrid tube amp / VPI table / Revel speakers. When the AC comes on or off in the room i hear a loud pop. I used to think it was a scratch on the album but now I realize its some sort of elelctrical issue. I thought it might be a table grounding ussue but now it also happens occaisionally now when I'm not playing an album. So does the amp need to be grounded? And to what? Thanks.
