there's a little noise comming out of the panning section of my a 109 vc signal processor.
when i listen to the vca it's there too, but not as loud as in the pan. 
i can even hear the lfo ticking with no cables connected. 
can i solve this leak?
can it be that the A-100 DIY kit #2  has something to do with it?
also: what's the "JP9" pins on the board? 


modules with these chips would be great! (small runs?)

+ for an effect project:
is there a place where one can stuff pcb's in small quantities (20)? 
futurlec does this, but only for a lot of pcb's...
