7 d$ P9 a0 w0 r$ e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。

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.6 f$ G- r, J- G2 _3 X

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
