So I have a question for you. I've been servicing a model 90 which one of it's failing's was the rf amp to mixer coil. Simple coil w/just two winding no taps. One side (pri) connects to the plate of the 24A rf amp and b+. The secondary connects to the grid of the 24A mixer tube. Primary is 92t 40ga wire and the secondary is 162 turns 32ga wire. The turn numbers are correct but the sizes are what I had on hand. Which one is going to have the higher resistance?

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!
