I found an old Tape Deck recorder that I tore apart to scavenge for interesting parts.
Two different kinds of solenoids left me wondering:
From an old service manual (not related to the tape deck recorder I dismantled) I found three different kinds of solenoids: 1. Fast solenoid 2. Pinch roller solenoid 3. Head base solenoid
What are the above pictured solenoids? Secondly, I've tried supplying a range of voltages to no avail. I cannot make them move. Any suggestions on how to drive these solenoids?
