Greetings from Oklahoma! I’m a younger guy that’s dipped my toes in a number of vintage tech, and have recently revisited personal cassette players! Big fan of Sony, the design philosophy behind the Walkman, and eager to learn more about these interesting devices. My collection is small, but I just acquired a wm-1 that’s mostly complete! If anyone has any tips on repair of this device I’d love to hear! (Play works, FF/RW doesn’t (prob plastic bits but idk best way to take it apart))
