The steel arbor which spins the disc on this model once had a felt-like coating on it which, when spinning the disc, prevented slippage and presumably dampened vibrations. The fuzzy coating was very thin and has gradually disintegrated over time. Bose Service tells me there are no longer parts supplied for this model. What material could I consider in attempting to replace this coating? It would have to be thin enough to maintain the proper gap between the pickup head and the disc.

Thanks.

Other than Very Thin you give no indication of the thickness...

You will need to be creative and improvise something from your environment - material (fabric) found in the home and easily managed glue. Fine abrasive paper perhaps?

Good Luck..., February 2017
