12 V power supply for AppleDesign Powered Speakers II

Anyone have advice for a suitable 12 V power brick to use with AppleDesign Powered Speakers II? I don't have the original adapter, and when I try them with the generic 12 V adapters I have laying around, I always get a loud humming noise. If I power them with a ATX bench power supply they are very silent. I guess the cheapo adapters take in a lot of interference. I tried to put a ferrite bead on the cord, but that didn't help anything. I don't feel like paying lots of money for a regular 12 V adapter...
