Noise floor has reduced-it was already low with the old idler as the table has been recently refurbed, the new idler just dropped it even more. Before, with my ear to close to the platter I could hear noise-a soft rubbing noise, now I struggle to hear anything. I don’t have access to a stethoscope to confirm. Will buy one and have a go next week. There wa no motor noise before or after I fitted the new idler wheel.
