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。' b6 `+ `0 O% `. T) d; {; [
控制转速的IC, SONY CX-032各脚电压值如图

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.  f- ^4 i  Z+ R& m
A rare Sony turntable TTS 400 has the same chip used as well.

<b>visitorj</b>, can you make a photo of the IC and the board please ? and the schema if you have it?

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.5 x; Z% {4 w/ h$ f
