Hi does anyone know if the MD and the MnM use the same power supply 
unit? I'm asking because I just got a MnM, but it has a 'noisy' PSU 
(does a little hum noise), and was thinking in using the one of my MD 
while I get a new one.

Where can I buy a new one?

BTW, does anyone know if a 'noisy' PSU could be any trouble in the 
future besides its 'hum'? Like it could burn or something...

Thanks
