Well after take a quick look at the diagram it looks like there using it to drop the filament voltage by using it as a 100 ohm resistor. The string in this set equals 106v It's going to have to dissipate about 15W that's why it's getting hot. They're calling it a "tube saver" I would say if it bothers you put a jump across it and replace the 35C5 with a 50C5.

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 it!
