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。6 p, D" ~, r3 n" o. q, o$ ^  T% u
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.  r9 X) A- z- ?7 S/ G6 j

有沒有用零件做出等效的主軸控制還要進一步追蹤
