+ x8 i. S' m. n" h0 N, J: A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。' n  E0 Z/ y" F2 _* H

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.' e5 b3 w9 O" _4 T* i9 N" V
A rare Sony turntable TTS 400 has the same chip used as well.

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.: b9 d7 G1 b6 ?7 L' J9 m
