Tom Boy radio battery information

I recently acquired a Tom Boy radio it seems to be in perfect condition and I would like to bring it back to life it has the original eveready nine lives B battery once rated at 67.5 volts. I would be grateful to anybody with information as to replacing or improvising a solution to my dead battery it seems like this radio would function if I could get it the proper voltage. Ive been having a hard time finding any info on this little radio I would be thankful for any kind of support thank you.

Sent you a schematic for a simple B supply.

Don't forget your radio also needs the 1.5 volt batteries for the tube filaments. Here is also a link showing your radio. Made by Automatic Radio.

Warren,
Can you send me a copy of the schematic as well?

Here are some ideas:

1) Connect 45 "AA" batteries in Series, similar to what BatPack.com does with 60 of them for 90 volts.

2) Connect 7 or 8 9-volt alkaline batteries in series. This will create a 63V or 72V

3) Connect 9 Ni-cad 9V batteries in series. This will output 64.8V as these batteries put out 7.2V each

4) Connect 8 9V NiMH batteries in series. These batteries put out 8.4V each and this will output 67.1V

5) Build this inverter circuit that will allow 67.5V to be output from 4 NiMH "AA" cells. This circuit involves adding an inverter containing a logic gate IC, some mosfets, some resistors and some capacitors, a transformer, and a rectifier.
