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。- h7 O9 |( J  r( C) L! T2 q
控制转速的IC, SONY CX-032各脚电压值如图

是IC坏了还是其它问题?如坏了,求着IC一块。谢谢!

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip." k7 E' M. ^) R/ t: O  j- s

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.

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.# @! V! I. q4 W% g: A+ o8 {
This will help all Sony R2R users in the near future as well as our machines age over time.
