Delta 66/Omni Studio wall-wart hum

[Picker]

I have a Delta 66/Omni Studio and the wall wart hums like crazy as soon as I plug it in? Does it always do this (normal?)? has anyone else experienced this?

I've had the Omni/Delta 66 for almost two years and never had that problem. Maybe a ground issue?

I also have had the Omni Studio for about 2 years without any troubles like that... definately not normal.

I have a wall-wart for one of my guitar effects pedals that has recently started doing that, and I refuse to plug it in anymore becasue in addition to a horrible hum, it also slightly vibrates. I don't plug it in for fear of it catching on fire.

Call M-Audio and tell them about it. Is it still under warranty? I am sure they would be glad to replace the adapter.
