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。* l# A3 X# T0 Z9 c. Q
控制转速的IC, SONY CX-032各脚电压值如图

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  T- {% B2 G4 @' A
This will help all Sony R2R users in the near future as well as our machines age over time.; h) n/ C& U$ K4 P0 \
