I have recapped this radio and built a dim bulb tester. When I plugged in the radio and turned on the tester with a 7 watt bulb, the bulb burned brightly. Obviously I have a short somewhere. Now what does a rookie like me do?

7 watts is too small; you need more like 60 watts for a 5 tube radio.

Johnny's right. I would start with a 60, and it should burn dimly. Radio won't play yet. Then put in a 75: radio "might" crackle a little. With a 100 watt it should start to play. Then you'll know you can plug it into the line. You actually can just use the 60 and if it burns dimly then you're OK to plug into the line.

Holy Crap. I used a 60, then a 100, plugged it into the line...and got sound. I used my body as the antenna and picked up a few stations, though with scratchiness. Who cares about scratched. It works!!! Thanks so much for the advice. BTW, did this radio ever have a self-contained antenna? There's a station whose antenna is right down the street, but that's all I can receive. And there's not much volume.

No, this set did not have a built-in antenna. For those following along, here's the schematic:

A 10 to 20 ft. piece of wire strung around the room should get you more stations. You may have to do an alignment for best performance.

7 Watts is way too tiny.
AA5 work @ min 25 watts, most transformer sets need 75-100 watts.
