ok i was given a zoom 707 it did not come with the plug... i have many plugs around but none of them seem to work as it wont turn on... i did try batteries and even with those it dont turn on.... anyone think its broken or just needs a power supply..

You need to plug the guitar input cable in. That's the power switch. I think it's 9VDC std 2.1mm barrel.
