Hi Skip,
> But cannot find a schematic
It's R-14 and it's kaput. As you can see it lowers the 120vac to power the heater string and dial lamp. So there are a couple ways to replace it.
1. Try to find a repl;acement tube.
2. Use a non polarized cap ( generally about 6-8mfd @ 200v).
3 Use a resistor to equal R-14.
So R-14= 133 ohms @ 25w & a 40 ohm resistor in parallel with the lamp so it will equal 300ma. R-14 will get very hot and is pretty big too.

Now I think I've got!
