>Power Transformer The highest resistance will across the HV winding(around 200-400ohms or so) next the 120v primary (10-30ohm) the the heater windings (just a few ohms)
Antenna Coil Pri pretty low 2-6ohms secondary pretty low also about the same.
Osc Coil Same as ant coil
Output Transformer primary 200-500 ohms secondary low a few ohms
IF Cans about 10-30ohms.
Mostly when you are checking the resistance of these items you are looking for a very high resistance indicating that the winding is open.
Generally with coils the lower the frequency the higher the resistance because it take more wire to make more inductance.

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 it!
