The player will convert AC to low voltage DC - you need to take it apart and connect the battery-pack directly to the power supply on the PCB.
Go in with a multimeter and find out what voltage it's running on.

Hi lemonie thanks for your reply i have managed to get it powered and i will probably put a instructable on soon, i used a bike with a lithium battery and capacitors and can generate enough electricity in a 2 minute ride for 20 minutes of portable record playing :)

Oh good, the Instructable will probably be a first of some kind, I've not seen this done before.

Yes it's called an Inverter. They are often sold for camping to take 12 volts and give out 240 or so at a low current.

Using AA batteries won't give you anywhere near enough current. It may work, but only for a few seconds. I would recommend using it with a lead-acid battery, it's the only way you will be able to get any kind of power out of it. What is it that you are trying to power?

No problem. If that's the case, I would recommend finding some way to generate mains electricity in bulk, as the batteries will be very expensive and keep running out. I would invest in something like solar or wind, or even just buy a petrol generator if you have to.
