Hi and welcome to the Phorum,
Here the service bulletin for your set: https://philcoradio.com/library/download...%20176.pdf There's the whole thing! In Philco speak what you have is model 44 chassis in a
B (baby grand) cabinet.
As for your question the missing cap is or was used to tune the field coil to eliminate hum. I didn't look at the service updates but
on a number of chassis these where eliminated. If you are going to upgrade the filter caps to 10mfd which is the common value
these days I wouldn't bother to replace #66.

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!
