It's a piece of cake! I use ten 9 Volts for the B+ and D's for the A that you'll have to find out what it is .
I have a Zenith 7G605 uses 9 Volt for the A and 90 volt for the B+ , so that's 6 D's for the A , and ten 9 volts for the B+ I have also two Philcos 39-72T and a 40-81T they ues 1 1/2 volt A and 90 volt B+, use two D's in parallel and then ten 9volts series .I can play these radios over 60 hrs on dollar store battery's, I use my vintage portables for emergences, flea markets ,or camping, you'll be surprise how well they play on pure clean DC voltage,
If you need any help drop me a line , you can buy what you need a "RADIO SHACK".
It's really eazy to do.
