( w3 u6 Y3 E3 F1 L  A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。

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

A rare Sony turntable TTS 400 has the same chip used as well.% g1 i: `! A9 U$ D2 y

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
