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 ]1 r. J3 }! }6 ?3 ~' Y8 b

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.& y$ |$ {! @% p: u

4 ~! W; C5 l0 |, A. uLuckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.- K* E. K6 Z  @. |7 [: J; f
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.# T; c: _. F- E+ a
