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。

是IC坏了还是其它问题?如坏了,求着IC一块。谢谢!

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.8 ^5 F; z% X" C! p
A rare Sony turntable TTS 400 has the same chip used as well.
