A five tube battery set, the sixth is a ballast so you can run the filaments from a wet cell or an Eveready Air cell. In spite of how it looks it may even decide to play if you applied power to it. I found the circuit diagram on Nostalgia Air:

It takes 67-1/2 volts and 135 volts for B+, -16-1/2 volts negative for C- (this is quite a bit most are only -4.5 volts) and the tubes use 2 volts for the filaments if you bypass the ballast.
