Re: No FM on one voice?

2008-09-25 by Karl

Hi ktfiz,

Lets hope it's not the AD7523. This part is rare anymore.I would bet 
it's the bypass capacitor Cx02. Where x is 2,3,4,5,6,7 depending on 
the voice number. It's a 2.2 uF @ 50 V electrolytic capacitor. We 
have seen the same value cap fail alot lately in expander/M12.   
Best Regards
Karl
