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。( Z& C0 B3 Y1 H. E+ T: r2 H! }. v6 C

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

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 E' ~/ i! ]( q" ^

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.2 a( r9 G, x: j
