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.

This is a great project.
My experience. I ran into difficulty building the power supply. An esteemed member offered and fixed it for free. Then I could not get my two preamp boards to bias properly. I put the project aside for a few weeks to get some rest. Upon returning to it I inspected my work carefully and found one solder bridge on each board. After reflowing and cleaning the joints, the boards settled and performed as they should. The good folks in this thread have been helpful all along. It was a long journey but well worth it - for the sound and finding kindness in others.
Several years later I am still enjoying Paradise

.Thank you all for your kind words.
Until I started this project, I wouldn't have considered myself a beginner. I have been building my own turntables and tonearms for a long time and have successfully developed, built and adapted various iterations of closed loop controllers for DC motors.
I have also successfully built a bunch of kits like this so far.
The boards look messy as I had to change a lot due to various reasons.
I‘m in contact with hesener so let’s see.

I am sure you both Simon and as_audio can, certainly I am not the only one. But let's see if I actually can do it
the proof is in the pudding!I am suspecting the boards are a little older, and so the metal surfaces (even though gold) are a little oxidized. And, the lead-free solder available nowadays isnt helping, either.
wish me luck!
