How to Fix a Sony Walkman WM-F5

Please turn on Closed Captioning (CC) for an explanation of what's happening in the video. The amazing Sony Walkman WM-F5 was the first in the Sports line. It featured the innovative Disc Drive, which always had an Achille's heel: the center gear, responsible for the motion of the whole mechanism, would eventually crack with age. In this video I revamp a rare black unit I bought on eBay,. What started as a simple gear swap quickly turned into a complete teardown - featuring cracked gears, custom 3D-printed lever rebuilds, a noisy volume potentiometer, and full rubber gasket treatment.
