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.( K- R" v  G( B" X  ^
This will help all Sony R2R users in the near future as well as our machines age over time.

有沒有用零件做出等效的主軸控制還要進一步追蹤

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
