Buzz,
A battery eliminator will not power an AA5, it does not have anywhere near enough current capability.
That being said, if you put 9 or 10 12 volt batteries in series, you've got it made.
Note that the radio will only work on DC with the plug in one way, but not the other. The reason for this is the action of the rectifier tube, which will only conduct in one direction when supplied with a DC source.
Also, the radio's performance on DC will be somewhat diminished, because you have the double whammy of the rectifier's forward voltage drop, combined with the fact that you do not gain the additional B+ voltage that you would using AC (110V DC minus the forward voltage drop is around 100V DC for B+, vs. 110V AC minus the forward voltage drop, but then mulitiplied by 1.414 (peak AC).
