Thank you! :D I'm just learning electronics and dove in without really knowing what I was doing. I bought a few basic electronics books so next time I mess around with something I'll know what I'm doing. Mike C.

Hello, I have searched all search engines and can't find an answer to my question. I have a Panasonic SL-SX480 portable CD/MP3 player that is DC only. It takes 2 AA batteries (1.5v for a total of 3v). I added an AC power input jack by soldering the wires to the positive and negative DC power points on the circuit board (where the batteries connect). I used a wallwart converter; the CD player wouldn't work at 3v, so I moved the switch to 4.5v and it works fine. The problem is that now, it won't work with batteries anymore. I have thought about making a battery pack using three 1.5v AA batteries and plugging it into tho AC power input jack I added, but that would make it not as portable as before (if it'd even work). How do I get the CD player to work with batteries again, and still keep the AC jack? Sincerely, Mike C.
