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。- t0 ]+ d- o- B" o% u5 v
控制转速的IC, SONY CX-032各脚电压值如图1 N  i& R4 V  Q- m. j* }' f& P/ ]

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.% O* A6 U- R2 T8 B( Z2 w
This will help all Sony R2R users in the near future as well as our machines age over time.
