Hey Guys.

I have an old Kenwood ka-6100 Amplifier. I bought it a while ago off ebay in very good condition.

After a year I started hearing distortion on the left channel after inspection I had found the idling current on the left channel was unstable and fluctuated.

After this I decided to recap the entire Amp and also found a transistor gone bad.

I replaced it and then all was well until recently the distortion came back and now when I push the amplifier the protection relay cuts the connection and then reconnects after a few seconds.

The amp also runs fairly hot.

Could anyone suggest what could be happening or what I should begin to test.
