Hi Rachelle ,
Your radio will need a couple of things if it's ever to play again . First as you already know is batteries . While the common B battery size was 45 volts (with multiple batteries used on multi tube radios , 2 batteries in series being 90 volts , 3 being 135 volts , and so on) the A battery will differ depending on tube type , not every tube has the same filament (heater) voltage . That's why JR wanted the tube number which is likely embossed on the tube base . To remove your tube you turn it counterclockwise by maybe an inch to disengage the metal pin seen in one of your side view shots of the tube in it's socket , then lift it out . Your radio will also need both a long wire antenna , outside the house if there are no local AM radio stations where you are , and a ground connection . In the old days folks used to ground them to a copper water pipe because those were all grounded , but with today's use of PVC piping even for water supply there is no 100% certainty of any metal pipe being actually grounded and so a ground rod is the best bet . Lastly ,providing the tube is actually good , your batteries are in order , and your antenna and ground requirements are met , you'll need something to listen to your radio with in the form of a set of headphones . Your radio has no internal speaker and being a one tube design it doesn't have the power to drive a speaker so a period correct set of headphones are what will be used to turn the radio signals into sounds you can hear . This is why many of these end up as nicely polished display pieces on a shelf somewhere rather than in actual use because usually it's only us radio collectors who will go to the lengths required to get one to run .

Hi Bill ,
I think they took some liberties with the drawing and a quick look at the tube in one of the other pictures shows the two different wires going to two different pins on the tube socket (VS the drawing showing them both on the same pin) . In actual application it's not unusual to see the batteries negative sides tied together to form a common return point for both the heater and plate voltages , with a switch in the - going wires acting as the power switch .
