My thought is that are several parts INSIDE the 2nd IF transformer. Two fixed caps (probably 100mmfd ea) and a 47K resistor. The 47K is in series w/secondary of the transformer. So if you measure from the diode to the top of the volume control that 47K is in series it adds to the total resistance measured. Typically the coil would be abt 20 ohms or so but perhaps the 47K has drifted up in value.
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!
