Bias setting for a Bryston 3B ?
I have an old Bryston 3B which seems to be really too warm on one side.

What is the bias setting across the emitter resistors for this amp ?

Too warm on one side could also mean a hf oscillation on that channel for some reason.

Also, if it's an old 3B, you might want to replace the electrolytics, there are a few sprinkled throughout the channel boards.
