dob, The OP has an Avid turntable and wants to know whether the Walker Precision Motor Controller can run it. I don't think he is in the market for a Walker turntable, or etc. Why do you warn against buying used? I owned a Walker Precision Motor Controller that I bought off Audiogon and used for more than 10 years and never had the slightest problem with it. Lloyd was always helpful if I ever had questions, regardless of the fact that I was the second owner. (In fact, he and I became friends over time. I first contacted him about an upgrade that he had introduced, and he was very cooperative about getting my unit upgraded, again despite the fact that I was not the first owner. He's a great guy.) On two different belt-drive turntables that I owned, it made a world of positive difference, and I would not have lived without it, once I heard its effect.
