I have a project I am working on that uses an old portable CD player. I want the device to run off wall power but the port for the DC Adapter must need a proprietary tip to fit in the hole. I have tried the multi-tip DC adapters with the adjustable voltage but non of the tips fit. The player I have torn apart calls for 4.5v DC In. Can I work around the weird fitting for the tip?
Have you looked on the player to see if there's a sticker giving the power requirements?
Hmmmm, back when I was at school, 1.5 x 2 was 3.... .... assume that's a typo..... usually those stickers show the external supply polarity
You would need a bit of overhead if the power tip is feeding a voltage regulator
