Default Krell KSA-100S left channel getting hot

Hi,

Both channels work, they sound same, but the cooling plates of left channel get really HOT compared to right channel.

I looked inside and couldn't see anything wrong. No obviously fried components or anything.

Any idea what it could be, where to look?

Thanks,
Tipo

Check the bias and you will most likely find that one channel is biased alot higher than the other.

Or it could be oscillating, but that usually reveals itself as poor sound quality and can kill tweeters.

I turned off the amp and let it cool down. When I turned it back on, the left channel had same temperature as right -> problem gone !?

In my understanding the only difference from start-up to start-up can be if the output relays don't always make good contact. Can that explain the higher temperature?

I try to get the problem to surface again and will then measure bias voltages.
