After all, we do live on a farm, or at least that is what the sign says coming up the drive - Tree Farm.
And, had anyone lived here prior to 1950 or even later, there would have been no commercial power. One of my neighbors still has his wind generator spinning in front of his house - I need make him an offer on that one.
The Rural Electrification Act of 1936 provided loans to extend the electric grid out to farms and rural communities. Like broadband internet connections today, there had been little interest in spending on infrastructure where few customers existed. Earlier, "farm radios" had to run on wind generators or batteries.
All of this makes them less than ideal for collectors that wish to display a working radio. AND it is likely that the power supply no longer functions. Which causes some people to reason "Rather than fix the supply that runs on batteries - that I don't have, let's convert it to - who knows - something else". These conversions usually result in a radio with missing or damaged parts, which was the case here.
To make things more interesting, the schematic shows the source voltage with reversed polarization (positive. ground). DON"T do that! While the syncroness vibrator supply will run with the input voltage reversed the filter caps across the output won't - nor will the radio.
Being basically lazy, I chose to only fix only the bad winding.
The magnet wire did not show the typical corrosion or burns from overheating. Instead the outer windings had become brittle, breaking many times as I unwound the failed 1/2 of the primary.
Now all I had to do was squish it back in there.
