PS - Motors in the home, like AC or house fans, vacuum cleaners will absolutely produce noise which makes it through the filters to produce _faint_ popping sounds.
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.

@mojo771 There is a bad capacitor in your air conditioning unit. It bypasses the power switch (in this case the thermostat). Because its failed, when the thermostat turns the AC on or off, a voltage spike that is supposed to be snubbed by that capacitor is what causes the pop in your speakers. Its not a fault of the electronics. |
+2 for Ralph. Have your unit serviced, they can clean it and check the voltages and wash the coil. That runs about $100, retail on a capacitor is $150-200 installed. Or change it yourself if you can safely. Do it now before you incur further damage to the air unit. I live in a hot area and have 2 large units. I blew a cap on one, and two weeks later on the other. Both days it was *110. One of the caps was only 2 years old. I’ve also encountered fluttering lights when a high current draw kicks on. This was a grounding issue. Depending on the age of your house you can also have tired breakers. I had a breaker for my pool get weak and it was sizzling on the bus bar. I replaced the breaker and had to move it to an unused position as the buss bar was pitted. I’m ok now , but I’m waiting on a new service panel as I have solar coming right after that. So get your air unit checked and proceed from there. Best of luck , Mike B. |
