The Old Ferroresonant MAGNATEK Converters...
These dinosaurs were 30X as common as competitive converters and were a flawed design from the word go... OEM chose the BW Magnatek units because they were the least expensive of the lot. I came a MAG...

The only thing I can think of is that Magnetek had dozens of designs. Adding a 100uf cap on the relay resistor unit output raised voltage .3 volt If it were purely linear it would not have done that nor should it have kept the same output voltage with wildly varying input AC voltages.
That's just the charging circuit, which was actually an option, but it's an add on to the purely linear converter. They used a couple of different designs for that option, but I have to dig out my paper manuals to tell the difference. I do remember they were a different option letter in the model number, and had very different capacities- one was 3 amp, the other around 10 or 15 amp (nominal, in a perfect world, during periods of porcine aviation :)).
