! k$ [3 F# ]# 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。
# X  g& s' O+ s3 V控制转速的IC, SONY CX-032各脚电压值如图

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.. A/ M7 h1 r. s" T6 g$ o; I4 P% K
This will help all Sony R2R users in the near future as well as our machines age over time.
