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。

是IC坏了还是其它问题?如坏了,求着IC一块。谢谢!

<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.' {# W: d+ A0 u8 Z; n" u
This will help all Sony R2R users in the near future as well as our machines age over time.
