9 j5 l: f6 {) ^8 A3 o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& Y' b9 C: Q; P
控制转速的IC, SONY CX-032各脚电压值如图1 E4 g* O; S. r% R; U, S

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip." v" U1 D0 v! @: ?0 f8 M8 X. z

( q$ M; o# s+ s# j" D9 o/ j& uLuckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.; Q0 l* |7 K! [
A rare Sony turntable TTS 400 has the same chip used as well.

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.

39.99美元 似無存貨 必須從其他舊機器拆 不過可能也是相同的毛病    -->  設計的弱點
