Hi and welcome,
Can't help you with the service aspect but can tell you a few of the
issues you maybe facing.
In 1939 thru 1942 Philco radios used
rubber coat wire. This was fine for the 1st 15 or 20yrs but after that
the rubber starts to fail. Some rewiring maybe necessary.
Electrolytic and foil/paper capacitors should be replaced for safe
operation and good performance. Not doing so can cause damage
to major components$$
The two end tubes don't require shields, some of the others don't
need them.
The 39-45 is fine sounding set when serviced properly. I have a
similar set from 1941 (41-300) it's one of my favorites.
GL on your quest for service.

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!
