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.

A rare Sony turntable TTS 400 has the same chip used as well.

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.5 F! ^0 l5 f/ P/ K+ J3 k" B
This will help all Sony R2R users in the near future as well as our machines age over time.
