Some great tips on here! - Im waiting until i build the dummy load but may also test the Ceramic Caps as said above. I think, in the end is to monitor all voltages under load since we do know that the IC's on the main boards dont like unstable voltages but would be great if someone could post up what would be acceptable voltages we can have from a fully working PSU?!
Its a real shame Behringer didnt come up with a better PSU or a 'fix' as this desk is still one of the best budget digital mixers out there
I personally dont really need a mixer anymore now i use a Safire Pro40 1U soundcard connected to a Behringer ADA8000 8 channel expander.......and now the studio is quiet once again! lol - But i still would like to fix my mates DDX since even though he has the same setup as me, he would like it for his drums.
If i actually get to build the dummy load and succeed in fixing the PSU I will post my finding but please also keep up your own findings and fixes.... Photo's also please!
Cheers again guys!
