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, _  N2 x: n( z' ^

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.( _( M, p% u7 f7 `# T" j- P
This will help all Sony R2R users in the near future as well as our machines age over time.2 _& q* M9 [& g6 Q0 s( w" V, M
