First post, so greetings, everyone. I recently acquired a Well Tempered Classic with the round motor. I've spent more than a few hours happily listening to it, but on occasion the motor will slow to a crawl and sometimes even stop mid-record. I have had some temporary success turning the Allen screw at the bottom of the motor counter-clockwise, but this hasn't seemed to effect a permanent fix. Has anyone else had and resolved this problem?
