Wooster Vintage Audio. Store in Akron and Wooster, Ohio. I heard they have a very good tech, an older gentleman.
Give them a call.

Vintage SS repair shop near Cleveland/Columbus/Detroit?
Also have an RGR 4-1 preamp with a major channel imbalance and an intermittent Phono 1 selector position. The rest of the pots and switches are fine. This one I have the box for, but no schematics.
Thanks for your suggestions!
