(The audio outputs of battery radios often used a tube of double the A battery voltage with a center tap...the ends of the center taped filament would be jumppered together to halve the opperating voltage and double the current)
I got it mostly as a curiosity piece as I've never owned a battery powered tube radio set before, and thought it would be an interesting piece to try and fix up.
