If memory serves me correctly the resistor is wire wound around the cardboard form of the capacitor. Typically wire wound resistors don't change value like carbon resistors. They are very stable under load even overload. I would suspect that it came from the factory that way.
When I've serviced some of these early sets I've just clipped the ground wire off of the cap. And soldered a new one in it's place (cap). The resistor is used to decouple rf signal from getting into the hv supply. The value isn't all that critical. Same with the cap it's job is to couple any rf signal to ground but not short the hv to ground...
If it oscillates when you get done or you can't sleep at night go ahead and add 100 ohms @ 1/2w in series.
Lot of working room eh.

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!
