Power Supply for Marantz-TT 15?

Is there an outboard power supply that can be used for the motor on the Marantz turntable? The motor (and the rest of the TT) is made by Clearaudio and I believe is the same one used with the Emotion TT.

I hear a bit of wow and flutter on some recordings - especially those that use piano. I know that some of what I'm hearing may be due to the pressing itself, but I'm sure that using some sort of regulated power supply couldn't hurt.
