Pretty sure why Philco uses one of the screw terminals as a speaker connection is not really for a spkr connection but as a test point. To measure the ac voltage across the vc to peak the IF an rf coils.
When my pals were reading comic books
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
Now I think I've got!
