Or in a bit more simple terms. Tune the broken set to 100 on the dial. Use a transistorize set set near the 7A8 tube to listen for a strong signal when it is tuned near 1450kc. The osc puts out a signal at 455kc higher than the dial seting. So when you set the broken set to 100 at equals 1000kc. The osc is running at 1000kc +455= 1455kc. Simple right!

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!
