After replacing all of the old paper and electrolytic capacitors with modern ones, and replacing a few broken resistors, and the dial lamps, all I needed was a replacement transformer. Buying one would have been a little expensive (about fifteen times what I paid for the radio). Luckily, the kind folks on the rec.antiques.radio+phono newsgroup were patient enough to teach me how to tell if one of the old transformers I'd been ripping out of old (free) tube TVs would work as a substitute. I found that I already had one that would work! It was a little larger than the original, and had to be mounted at a slight angle to fit, but the radio now works perfectly, for both AM and shortwave reception. Actually, they say restored radios work BETTER than new, since our modern capacitors are better than the old ones. And there's no denying that tubes produce a different sound than transistors. I find it to be somehow warmer, fuller, richer, fatter. i.e. better. Maybe I'm biased. (Or maybe I'm just dreaming about food and prosperity?)
