Your welcome!
Most sets will have a cap there to prevent the output stage from going in to oscillation. Philco may have thought that there was enough distributive capacity in the winding that it would not break into oscillation. And in 1933 the cost of that cap .15c could buy you lunch. The common value is .01mfd sometimes you'll find a.02mfd. I find that both size tend to make less bright (cuts highs). So I'll adjust the value to my liking.

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!
