" C0 I2 V8 D, c2 T  k, e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。

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.! z8 R* Z1 E- o, U3 e3 r
This will help all Sony R2R users in the near future as well as our machines age over time.
