New to me 610II - Distortion

[Kapco]

Exactly what I did. 1v peak to peak.

Have you tried and actual audio source and speakers ?

Yep...sounds very distorted. Reacts the same way. It won't output much volume either.

Both channels look identicle ?

Yep, exactly the same. Doesn't matter if I test it through the R or L, same exact scenario.

Yep...I have the -42v at the junction. If I check the voltage between D577 &D578 I get -21, and if I check after D578 I get 0v

Are you seeing -42 volts at collector of TR572 ?

Yep. -42v at the C and -66 at the E&B

I'm going to have to sleep on this. Its getting late here and I have to get up early in the morning.

Yeah..no problem..I am going to crash out soon too. Appreciate all the help on this. I'm stumped.
