I have bought a Mcintosh C28 (110V). When I connected it to my gears, I found that there was a electrical noise coming from right speaker. The left speaker is quiet. I can still hear the noise when I stand back around 4-5 feet. Any idea can reduce that noise. Thank you.
I did diy amp before. But I am a diy beginner. So it is hard for me to trace the source. Well, now I am testing different senario which part cause the noise. let me update later. thanks Alcat
