Still sounds like your local oscillator it's running. Verify by using a counter connected to the grid cap of the 24A mixer tube or have a listen for it in a working receiver @ dial frequency + IF frequency. Place the working set's ant lead near the 27 oscillator tube.
As for the wire wound resistor you may have to disconnect it from the circuit to get an accurate reading. Generally they are pretty reliable.
Saw something wrong on the schematic, the 47 tube has the internal connection from the screen grid to the filament tap. Should be the suspresser grid not the screen.

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!
