( C- [. J1 ?: k: a" y9 M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。6 U+ E$ E/ h, p9 ]0 ]0 C

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.: R& G9 `; m9 R0 ?) V; X5 H8 ?

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.
