; b, x5 w& R7 y2 X" G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。/ K$ e( {$ V8 M+ ^. b# y' W
控制转速的IC, SONY CX-032各脚电压值如图

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., D7 W) Y1 w0 a" h( e
