Hello. I have a pair of b-12 mono amps running very hot. One amp is running at 152mv of offset and the other is at 720mv. Proper settings (found in another post) appear to be 120mA bias/5mV offset. I have searched extensively and cannot locate a service manual, just schematics. It seems clear how to make the offset adjustment but I can not figure out how to make the connections to test the idling current (bias). Does anyone know how to adjust the idling current including the location of the test connections? Attached are a few pics of the amp where the idle current pot is located and a schematic.
Here is a link to the schematic also
