If you measure the resistance of the coils in the IF transformer that will tell you if it is bad or not. Double check to see that the 10.7mc IF coils are not affecting your measurement. Most tube AM/FM set the IF are tied together so they don't have a separate IF amp tube for the 455kc and the 10.7mc stages. Also check the voltages around the 1st and 2nd IF amp tubes to insure their proper operation. You may have a bad screen resistor or cathode resistor.

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!
