/ g4 Q/ J/ o& X0 \: v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。# B" z# J* Y) @: |5 E

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.  f! `7 D0 U+ P9 e" d

39.99美元 似無存貨 必須從其他舊機器拆 不過可能也是相同的毛病    -->  設計的弱點
