; @% @/ T) G- U: ?! N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。# a& V& a% x; ~: S3 g
控制转速的IC, SONY CX-032各脚电压值如图

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.1 K7 v/ o! L$ G6 q5 H1 U  F
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
