- X2 e9 C* N. c" \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。

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.- k2 S8 e* R& @7 a4 M. ~" ?* o
A rare Sony turntable TTS 400 has the same chip used as well.
