I am looking for a cord for my emerson stereo with a 3 beam laser pick digital cd player, a cassete player and am/f/ radio with individual speakers. I think it is a 2002 model number PD6721. it is the cord that connects the system to wall plug. Don't laugh. I am not electronically minded so I don't really know the terms. I know all of the systems work because I tried it with batteries but those things are so expensive, I can't afford them. Thanks much any info you are able to provide. Jean O'Toole
