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。! P4 H7 C- J0 N+ \0 ~  Q' Y4 f) a
控制转速的IC, SONY CX-032各脚电压值如图1 }0 I- X8 x" s' g

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.! W) v# k8 b7 K) k- B

This will help all Sony R2R users in the near future as well as our machines age over time.
