Hello all.
I have extensively repaired this amplifier and all is well and working good.
I was wondering if somone knows what VR102 the 5k pot is for on the board? The service manual does not mention adjustments.
In the parts description it is called volume? Does this need to be adjusted and how is the proper way. I have not moved it from the factory setting.

The front-panel pot next to it is VR102. Look at the resistors (R153 and R154) connected to the outer terminals of the trimmer. They are the ones connected to the DC offset pot (VR104) on the diagram.
You connect your multimeter across the positive and negative speaker terminals and adjust for the lowest possible DC voltage.
