Buzz/Hum from Cary SLI-80

I used to own an SLI-80 and it was silent. Is there a cable tv coaxial cable nearby causing the hum?

Should be dead quiet. Make sure transformers are not loose. But be careful to discharge power capacitors before opening the unit, as the voltages are dangerous. Also, call Cary for technical assistance. Good luck.

Sounds like a ground loop to me. Try a 3 prong to 2 prong adapter on the AC cord. Also called a cheater plug. You can get them almost anywhere. Radio Shack, Home depot, the grocery store...

Best thing to do first to be sure it is the Cary is to disconnect all components from it and plug it into the wall (if you have done this already my apologies). Is the hum still there? If yes then it is the Cary, if no, something further up the chain is causing it. Add one component at a time starting with the PS Audio until the hum appears. Cheater plugs are great for diagnosing the problem. You'll read all sorts of stuff here about the positives and negatives of their use on a permanent basis. I don't like them as a rule but sometimes you may just have to live with them, or get a balanced power conditioner.

cheater plugs can be a fire hazard.goolge jensen transformer "ground loop isolator" ...worked for me
