& N& U5 t6 T3 q" v0 q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.' b* o) L6 F/ N% q" Q& S3 E0 }/ D
This will help all Sony R2R users in the near future as well as our machines age over time.
