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 u" s& z2 x3 m) Q- ^1 Y. m& J
控制转速的IC, SONY CX-032各脚电压值如图

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.: ~, b0 g$ A- D, M7 P; r
This will help all Sony R2R users in the near future as well as our machines age over time.4 [! X, b6 W- V( J/ N8 T
