Glad you got that sorted out. What did you end up with for bias voltage?

I forgot to check voltage I was so happy I got the bias mA in check and amp was sitting idling so happy and no noise. Played for about 15 minutes.

Some photos

I only had axial 10uf/100v caps so used those. In another 3 years I could replace those caps if I order then now.

Replaced R30
Replaced R28
Replaced R7
The big resistors you see in the photos :)
