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。: A0 v4 @4 k/ c7 k# [& j  o5 K$ A: c: I; N

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip., [* T+ A/ v, I3 ]0 H8 p
A rare Sony turntable TTS 400 has the same chip used as well.
