2 @  @, ~, w6 q/ l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 I' q! E" F. X& ~% e" S

<b>visitorj</b>, can you make a photo of the IC and the board please ? and the schema if you have it?

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.
( U& S8 e4 F/ n9 ZThis will help all Sony R2R users in the near future as well as our machines age over time.
