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.% M) k, b5 Z8 J# h

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.
& q6 F- D- M" oA rare Sony turntable TTS 400 has the same chip used as well.
