4 \( a- }9 O) s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。0 `' A9 X; _7 q& B8 h/ p
控制转速的IC, SONY CX-032各脚电压值如图

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.# e% ^0 y" ~; a- r2 R

" c# G/ j5 Y! o$ K8 PLuckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.* ]# G; D, J' z; `
A rare Sony turntable TTS 400 has the same chip used as well.
