Hi Bud and Welcome,
Give this a try https://philcoradio.com/library/index.ph...chematics/ Click on 511. If #70 is missing you should be able apply an audio signal to #24 and hear the signal thru the speaker if all is well. 70 provides the hv to the 27 tube which is the detector. That's why for now the set isn't receiving, there maybe other issues. Would go through and check all of the pin 2's of the 26's to see if you have hv there. In good working order about 135v of lower the bypass cap connected to it is leaky. If 0 the coil is open and will require a rewind.

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 it!
