/ c3 Y" V. F6 i; i. {7 D新年捡了部SONY TC-580,遗憾的是主马达不转,经检测怀疑是转速控制电路故障。如如图加一个电阻,主马达会转,改变阻值便可改变马达转速,但转速很不稳。, R# Y; z' w' @" R7 O5 H/ k
控制转速的IC, SONY CX-032各脚电压值如图2 O; [0 Q1 q; f# _2 d) j- C, p

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.
