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。# [9 V% d6 W0 _/ g& N8 Z0 `+ R+ Y

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.4 U- F1 {& m8 K0 O' R1 S

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.1 J# G6 {) H' l
