My model 1700 B&O T.T. is running slow. Here's my question; Should there be a belt guide on the motor spindle? The guides I have seen are brass and fairly thick. I think this would speed it to the proper rpm. The belt is currently running on the motor shaft itself. It seems a little loose to me. I haven't had this very long and bought a new belt, installed it, then checked the tt out. Any help on this would be appreciated. Thanks, Jim
