Reply to Loose power socket on Xone:22... what do

Bought this guy used a few months ago, back then I fixed the right volume fader and that was rather straightforward.

Recently, I've noticed that if i'm playing out and the mixer so much as gets bumped, the power flickers for a second (sort of like when earbuds begin to break with an iPod) and causes an awful speakers pop. It only happened once in a great while a couple weeks ago, but not it keeps happening multiple times during a set, pretty big problem.

putting very slight weight on top of the connector to the power socket fixes this problem, but it by no means a long term solution and is probably making the socket even looser...

Also, it is possible that it is the power cord that is breaking, maybe the tip is broken.

Anyone have any idea what I should do? can't imagine this is as simple as replacing a volume fader...
