Look at this magnificent glowing red dial, visible through its plastic magnifying lens!

When I received this radio, the power transformer had been replaced (I'd guess sometime in the 1950s) with a replacement unit that was physically too big to fit properly. It was sticking out the rear of the radio by almost 1/2 inch, deforming the cardboard back. Since this was an obviously unacceptable situation, I set about finding a suitably sized replacement. I couldn't find a small-enough transformer with both 5-V and 6.3-V filament windings, so I had to settle for a tiny replacement unit that had only a 6.3-V winding. (It can be seen at left through the cardboard back's holes, on the right side of the chassis.) Luckily, I had next year's 1939 technology to work with, so I was able to modify the circuit to use a 6X5G rectifier instead of the original 5Y3G.
