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。4 W/ Z: Q+ H) t+ V) i) K
控制转速的IC, SONY CX-032各脚电压值如图

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

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.
5 S1 S$ f5 k& tA rare Sony turntable TTS 400 has the same chip used as well.
