Sob, my shark's power supply has mislaid its blue smoke and is refusing to 
function without it.

The one I have is a 5V 6A job which seems quite high (current wise).  Does 
anyone:

A) Know of a suitable source of replacements?
B) Operate their shark on a lower rated unit?

The disk on mine is powered externally; but I can't source power from 
that, unfortunately, since it's in a separate enclosure.
