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 Z" \' _* Z5 E3 ]; G
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.; t* P$ d, W$ a% C
A rare Sony turntable TTS 400 has the same chip used as well.$ }2 h, w( [6 |7 _' C, P
