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。& w! t* G! }' v0 \: r
控制转速的IC, SONY CX-032各脚电压值如图

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.) y* v# @9 T; Q; M$ [. j

/ ]+ Y5 t/ U( SLuckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.! j, W: {. F$ L7 S
A rare Sony turntable TTS 400 has the same chip used as well.
