控制转速的IC, SONY CX-032各脚电压值如图

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.( Y1 {' m0 R7 d8 n% `$ j% e
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
