求助：主马达不转
本帖最后由 大头猪 于 2012-1-3 21:39 编辑新年捡了部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。
控制转速的IC, SONY CX-032各脚电压值如图
是IC坏了还是其它问题？如坏了，求着IC一块。谢谢！

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.
A rare Sony turntable TTS 400 has the same chip used as well.
The supllier on this link has the IC listed.

<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.
This will help all Sony R2R users in the near future as well as our machines age over time.
Kind regards, Raymond
有沒有用零件做出等效的主軸控制還要進一步追蹤
零件追蹤

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
谢谢！
