% f* |: L* a- v" B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。: _: k! M# p. w' R1 J  ^( R$ M

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.  T2 z' ]. P: A* K, |

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