Linn LP12 Turntable; Motor Speed Problem

I'm asking this question for my father. He has a Linn LP12 turntable that needs professional help. He lives in PA, roughly 45 minutes from Philadelphia. He's not opposed to shipping, just thought there might be someone he could drive it to.

The board is no longer regulating motor speed. I hear that this is a common occurrence.

Any reputable person/place would be greatly appreciated.
