I am guessing it is designed to work on 12VDC, maybe 6VDC. I would look inside and see where the power wires went. If I could identify something that set a requirement - like knowing that the power line went directly to 12V filaments - then I would feel comfortable knowing what the input voltage was supposed to be. I expect the power line drives a vibrator which then drives a step-up transformer, rectified to produce B+. That's probably what supplies anode voltage for the tubes. But you gotta look and see. If you're not very technical, maybe there's an old-school TV repairman in your area that can help.
