1 _* J6 ^& m" ^$ J7 ]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.
3 A1 n& P5 o: J, G. {) r6 u+ ~9 W2 K4 C$ o7 h' f
Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.+ p/ \& `/ _' J4 M! b: ]; o  a
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.
