( h2 w7 k% `0 n$ o# ]- p, J# m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。  w9 @6 b) F7 N
控制转速的IC, SONY CX-032各脚电压值如图3 o" L, |; O" O5 N

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.2 T4 z1 c% I& w7 V

A rare Sony turntable TTS 400 has the same chip used as well.

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.4 h2 D/ b4 T! ]3 o0 W
This will help all Sony R2R users in the near future as well as our machines age over time.
