O.K. - I just went into my brother's room and copied down what it says on the Motorola power "brick". I'll try to relay only the relevant info - it looks like a switching power supply:
INPUT: 110 - 127V ~ 60Hz 0.25A
OUTPUT: +12V - 750mA
Also, on the Digital Adapter itself, right where the cord from the power supply plugs in - it says "+12V DC IN"
So am I good for switching to a linear supply (that is - if I can pull it off)?
