5 y6 o" T2 W2 U5 b$ 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。1 q5 c& A% @2 x* @& x9 }) _

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.0 S, m- t  y, B/ l" |/ N- C+ h# k
A rare Sony turntable TTS 400 has the same chip used as well.
