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 }3 _( q/ k7 m5 K- P5 h

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.8 E1 Y6 v/ Y4 x# ]2 v
This will help all Sony R2R users in the near future as well as our machines age over time.4 X$ i5 {: E) r& C2 i: H
