Realistic 2100d problem!

What do you know, the 2100D service manual I have here at work is the one you have.

Pin 7 of the protection board is for the right channel and pin 2 is for the left.

VR501A is the offset control for the Left, and VR501B is for the Right. (Red boxes) Again just little tweaks and let it settle.

To be safe I would put electrical tape or shrink tube on the screwdriver shaft so only the metal tip is exposed.

Offset specs are no more than + or - 15mVDC, target is 0mVDC.
