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。4 G' u3 h3 H1 H! c) Y. N
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.

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.0 `; g3 H" L9 U- n% o  t# `+ h* E# Q( l( x
This will help all Sony R2R users in the near future as well as our machines age over time.

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
