* Q& d. l+ N2 |9 B% c' X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。7 ]0 {( K" u4 r7 ^! P

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.- E% t& ^; |! G* e1 j. b5 X0 L
A rare Sony turntable TTS 400 has the same chip used as well.
