DESPITE Simon1972 and others attempting to help you have NOT posted the pictures they need
to help you overcome the problem.
I know that Simon1972 has built and or repaired a very great number of these Paradise head-amps.
To call it "the worst project ever" is - in my opinion - totally unfair to the designer and to all of those who have tried to help you.
I suggest that you post pictures (Possible????) and see if there is - to those who know these things - an obvious answer.
