Converting an old Studebaker car radio to a home radio

The radios that had a non-syncronous vibrator would run on either polarity. If you look at the schematics in Riders, they show how to change the polarity connections if the radio did use a syncronous vibrator.
I've seen a radio that was powered by a large 6 volt transformer, that used only half of the primary of the vibrator transformer. It seemed to work OK.
