I aquired a used A-110 that does not output any signal. I have traced
the board with a scope and found a point near the BC559 marking that
outputs saw wave. I assume this is the output of the saw core. Since I
am not finding signal anywhere else on the board I swapped out both
TL064s. I have not swapped out the CA3046 I am curios what othe
critical components I should look at to narrow down my search. Any
particular transistors or Electrolytic caps. Also, what happened to
the A-110 sevice manual that used to be on the doepfer site

Thanks!
