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。

Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.- g/ ~6 h7 E' \( l/ g8 ~
A rare Sony turntable TTS 400 has the same chip used as well.

<b>visitorj</b>, can you make a photo of the IC and the board please ? and the schema if you have it?

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.1 L/ f% _( Z% Q
This will help all Sony R2R users in the near future as well as our machines age over time.
