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 G# B5 ~/ C% ]1 i1 m  n

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.8 \& X( w; V1 l1 W

' L! F, U" f9 f7 j: NLuckily 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.

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
