* Y1 g  u* {2 j3 p* h7 G" o! W' D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。6 y3 H) S8 N; C& N) ?6 {0 H

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.- b! v. z! L. r" p+ o- m- Z
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
