Philco 20 restoration state: need the voltage chart
#18

A few thoughts. If all the resistor are good then I would check the ground rivet. Sometimes they can develop a high resistance. The other thing is I've seen on some of these diagrams/voltage measurements the - lead is connected to the cathode rather than chassis ground.
You mentioned how the set sounds, try hooking up a modern 8 ohm speaker to it. It really sounds great! The spider and paper on the original are pretty stiff thus inhibiting the frequency response.
By the by are you from Wallace and Gromett land?

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!
