A very nice looking WM-F501 has been waiting for a service / repair. Currently the cassette part is currently not working, while the radio is working. See the pictures below, from every angle, rollers, capstans, and head, for the condition. No visible corrosion in the battery compartment or rust on the capstans. I cannot detect a crack in the large gear. Upon request and with a fair offer, I will send a video with audio of the radio, working while the unit is powered by a gumstick, connected to external speakers. Volume and tuning operations are without crackles.
