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。, z  {8 c2 L/ ?

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.+ {5 X$ c: h1 m8 A/ L7 o8 p3 h! e
A rare Sony turntable TTS 400 has the same chip used as well.
