In a quick look at your pics in another thread, I see you have the loop installed with the component side facing the tube sockets. Upside down compared to the loop instructions. The loop board has a built in ground plane, a shield ,on its bottom side. With your board upside down like that, that shield is useless/defeated.

So, try flipping the board around 180 degrees as it is shown in the loop instructions. Sounds like you are still working through other issues, but this should help remedy your issues here.
