If you can give me the voltages for the B section and A section of the battery pack, and the dimensions of the area it fits, I can explain how to make yourself a suitable replacement. I guess you will have to get a schematic first to find that. Also, you might try posting this in the "electronic repair" section. It might get more notice by the electronic restorers. You can see how I rebuilt the battery for my own Philco portable here :

Agree, get schematic, find out voiltages needed, and you can put together inexpensive 9 volt batteries for B+ and a couple of C or D batteries for filaments, and AA's for bias if needed. Else you can build easily a plug in battery elimiter, tons of stuff here and on web. Posts already given are great advice!
