> The dial indicator is pretty decent, just warped, maybe a heat gun can straighten it? Also the speaker cone looks like it may not be the original with that one tab sticking out?
Have used a heat gun but be careful keep the heat low and don't get the dial wet.
Seen a number of Philco sets w/ the tab.
> missing electrolytic condenser
If you can't find an original a more modern Twist Lock cap is the same diameter. The base is slightly large but should clear the chassis w/out a problem. Value doesn't matter as your going the restuff it any way. If you get a 2 or 3 section unit you could put both caps in one can. Bare in mind that neither - are connected to the chassis but go the hv center tap.
<The wire vs. resistor on the condenser
No it's wired correctly. #8 has two sections that the bare wire is used to connect them in parallel. When restuffing use two .1mfd caps.
>To test the Oscillator Transformer
The simple answer is that most of the time the secondary is the problem. Once you get it ready to power up you can measure the voltage on the screen grid of the 6A7. If it's 0 your coil is open. Generally the IF transformers not a problem.

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.

Now I think I've got!
