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。- O5 n% C  U' s9 o9 ^: s8 `; v6 Y

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.+ V& A5 o, k* g3 q! T4 l
This will help all Sony R2R users in the near future as well as our machines age over time.
