& Z& o& N. ^/ m, d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。5 d' C2 Z* L0 ?% K/ U0 R' s
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.3 D7 F4 n& `6 u9 B
This will help all Sony R2R users in the near future as well as our machines age over time.! t$ k4 W1 j# b
