1 M- V1 y+ V# j5 e( C2 x; O% r. o2 v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。: V8 v, g/ p+ y( F! X
控制转速的IC, SONY CX-032各脚电压值如图$ m" t. {( N3 r: n

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.  c6 K0 x9 r# J4 \3 y6 l( w9 k

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.

39.99美元 似無存貨 必須從其他舊機器拆 不過可能也是相同的毛病    -->  設計的弱點
