Okay, so I built this kit not too long ago, and it sounds wonderful:

But the issue is, its powered by a dual 12v AC output from this transformer:

While the transformer is a perfect match rating wise, I'm getting the feeling that the ripple from the AC supply is causing a hum to be audible in the speakers. Not only that, but I'm wondering if having the transformer so close to the amp is also part of the problem, due to the electromagnetic field its creating, am I correct?
Really what I'd like to know is how I can cancel out as much hum as possible so that listening at low volumes is much more clear. I have ideas as to the direction I should go but I'm a bit confused as well. Something to smooth out the ripple as much as possible so that there is no audible hum from the switching in the AC lines.
Thoughts?
