To simplify what Morzh (Mike) said your set has 3 different style tubes in it. Those being 4 pin, 5pin, and 6pin. 4pin tubes and 6pin tubes have two fat pins. On the 4 pin jobs it's pins 1&4 and on the 6pin jobs it's pins 1&6. these would be the heater pins. The 5pin tubes are a little trickier it's the two pins that are closest together pins 1&5. Any questions you can google 37 tube or 76 tube which are the two 5pin tube your set uses.
The way Philco set up the schematic for the 116B (big honkin' table set) and 116X console) they share the same one for the most part. The physical chassis is the same but some of the parts and layout are different. Also bear in mind that this service information was meant for service techs that were working on radios day in and day out not hobbyist 80yrs later. The question does pop up from time to time where can I find a good sharp clean schematic of my radio. Unfortunately we're are the mercy of the 1920's and 30's draftsman good bad or indifferent. I find that the Philco ones are pretty good, the part location numbers are hard to read a lot of the time but the drawings themselves are good. Try a Crosley one time it'll make your hair smoke! There are three different sources free I know of the Library here, Nostalgiaair http://www.nostalgiaair.org/pagesbymodel...013123.pdf most of the time they are pretty awful do to the scan rate and https://www.americanradiohistory.com/Arc...36-PQR.pdf Scroll down to pg 24 of 302. That one is pretty good and has the service info too.

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!
