hey i know this should go somewhere else like gear and acc but i didnt know where to put it
i need help finding a replacement power adapter for a casio cdp 100 its discontinued now and the power adapter is supposedly hard to find it.
heres what it says on the site

Power Supply AC Adaptor AD-12
Power Consumption 12V - 18W
Dimensions 52 2/16 x 10 15/16 x 5 3/16 inches (132.3 x 27.8 x 13.2 cm)
Weight Approximately 24.7 lbs (11.2kg)

im gonna go to a radioshack and see which one would work but i dont know what i need to know like watts? amps?

all it says on the piano it self is 12v and +(o - for the polarity.
any help would be appreciated.
Send me off to bed forevermore.
