Hello, as I already wrote in the introduction forum: I just received a Sony WM-DD22 of eBay. The overall state of the unit is ver good, it only has a faulty fast-forward button: When a cassette is inserted and I press FF I can hear the sound of the motor spinning inside but Ican see through the small Plastik window that the axles inside are not spinning. Rewind works perfectly, only FF ist faulty. Do you have any suggestion where I have to lookfirst when I disassemble the device? I don’t wantto completely take it apart when I don’t have anyclue what specifically to look for. Thanks for any advices! Greeting Nico
