The servo balance circuit may need to be adjusted due to aging components. This circuit takes care of the V5-V8 tubes.
This normally does not need adjustment unless you have moved the pots previously or changed tube types. Make sure you use a plastic adjustment tool for this task.
The bias is just for V9-V12 tubes.
Tubes should be matched set for best performance.
