Here's what was done right after the war. You may find some of these circuits added to your set. In those days 120 to 24v transformers were rare now a dime a doz. I would bother to rewire the heaters just use a 24v trans.

See pg 29

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
