Krell KAV 300i Problem


Hi, everyone,

My beautiful Krell KAV300i has started to show some issue recently that I hope somebody here can address the problem. Well, I can explain the problem as follows;

1- Amp is on, nothing connected to the input jacks, when I get closer my hands or touch one of the input RCA jacks a very high, annoying hum starts,

2- Amp is on and I play and listen to something thru one of the single ended inputs without having a problem. But when I switch to an empty input channel annoying hum starts again.

This probably happens to be a grounding problem and just have occurred very recently. Something has failed inside the amp but what would it be? I have been using another system using the same AC outlet having no problem at all. I also tried this amp in another room but the problem was still there.

I’d like to have comments on this.
Thanks.
