Weird pedal board problem

[Barry gall]

Hi

Hope someone can help.

I have had a pedal power running a large pedal board trouble free for years. Just recently it’s started playing up. Runs fine for about 40 mins and then I get this intermittent signal fade. Very much like a flat battery in a pedal - but I don’t use any batteries. None of the pedals are moved, disconnected or anything, all I do is plug in an input and output and power.

Help!

I’m running tu-2 - ns-2 - vox wah - Rocktek compressor - ts9dx - ge-601 EQ - Nano pog - ns2 (return) - Washburn flanger - ch-1 - d-seed delay - 720 looper...

Really don’t want to rewire all of it...
