# ~6 m- N7 W# i; G" w8 d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。5 P8 u, s: x; G; K3 ^- @% R
控制转速的IC, SONY CX-032各脚电压值如图

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.- Z9 X  g5 P% S/ u
A rare Sony turntable TTS 400 has the same chip used as well.
