Hi,

I have a Bel Canto Evo 200.2 amp that had a bad relay which caused no sound to
come out of the right speaker. I sent it in to get it fixed. It was a cheap fix
(~$100). But now when I power on the amp, there is a loud audible click through
the speakers and there is a hum. This is independent of whether the preamp is
powered on and I'm playing something or not. I have the RCA/XLR input in the
correct position and I'm using it as a stereo amp (not bridged mono).

I contacted Bel Canto about it and they're unable to determine why the hum is
there now as opposed to before. I wonder if any of you would have some
hypotheses that I can test. I tried putting in a Monster Cable outlet
(Powercenter HT800) and tried moving the outlet to other places in the
house. But the hum persists.

A related question is whether this hum can damage the speakers in some way.

Thanks,

Dinesh
