      Mr. Doepfer. I successfully changed the A-190-2 Q1 resistor by replacing it with a BC547B transistor and the gate output is now working. But I think that the CV V/V output is not working. Is there any piece I can replace to fix this?



Thank you,



Sidney

      Hi Bakis

it is not only Sidney. Also your mail appeared twice at my mail account 

(not on the web)! It happens with around a third of all postings and
