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。9 c8 N+ `2 u8 a0 f# N
控制转速的IC, SONY CX-032各脚电压值如图

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.

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.9 s9 m; Y" c0 U5 N4 G3 o1 O
