# S% s. H8 E5 P, Y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。; c( ~- g" P, U4 ~! t
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.0 Y3 ^8 [* d7 {

% d7 z9 ]( m1 l) k2 eLuckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.: Y; [4 l, s2 e( C3 ^
A rare Sony turntable TTS 400 has the same chip used as well.
