0 f: u, i$ D0 J3 u2 b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。& k( h% O9 _" n$ y% q+ g

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

This will help all Sony R2R users in the near future as well as our machines age over time.
