' ]- z- W5 U. c+ g- h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。9 c1 h# ?& A9 C# O6 S. e

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.# L0 y" u" y" l* Z/ S, ?

& z3 u8 s1 G/ @Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.

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.
