% u1 i' _! t" d7 u8 X, I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。

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.1 ?; W3 n  S8 n" ~

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.( E5 }5 Q( H! r
This will help all Sony R2R users in the near future as well as our machines age over time.
