I have a 5 tube radio with "JEWELL" on the front, not Jewel. Looks somewhat like a small coffin. It is 31 1/2" length by 12" deep by 10" tall. All tubes are o1A type. There is a compartment on each end, no holes leading out. Long slot entry on back to feed the antenna, ground, speaker, and battery leads. Five knobs on front. Nothing else to identify model. Appreciate help on this. Can e-mail picture if you think you can help.

Hi Bill

Radios like this were popular around 1925. Rider has very few schematics for these radios. You might check Stewart Warner 300 series schematics. Radios from the time are similar.

Your Jewell is made to operate off batteries. You will need a little over 5 volts for filaments. (Originally a 6 volt car battery was used.) The radio will also require "B" voltages, around 22 1/2 & 90 volts. Some radios used a 4 1/2 volt "C" battery.

Thanks Norm,
I got an old Franco Three in One Battery with it. Has 3 or 4 1/2 Volt, Yale Electric Corporation. Good display piece. In case pictures may help anyone tell me more, here's two.

Norm,
I'm wrong on the compartments. From each a hole leading to connectors inside case. The compartments are for the batteries. You know I just had my eyes checked, I need more lighting.
