Hi!

Welcome to my DIY audio forum. The forum SW has been reset and unfortunately there were some problems with backup files so a few posts were lost, nothing important though.

Those pots are for trimming the bias of the output stage.

Of course! This is a servo amp and I can guess the trimmer is for bias, but how? Please advise.

Trim for decent temperature, "not too hot" and hot may be 50-60 deg C.
