Hi Rachelle,
In addition to all the good information given you, I'll throw in my two cents.
You most likely have a regenerative reciever. Many of those old 1920's battery sets used two 22 1/2 volt batteries to come up with 45 volts total for the "B" supply. The lower voltage can help to reduce howling and squealing in the head phones when listening. With a good antenna your type of radio should even work with about 24 volts for the "B" supply. I have been able to go as low as 16 volts, just for testing.
