Hi and welcome,
Connect your well calibrated signal generator to the ant post. Set the radio's tuning dial @ 550kc or so. Generator for 460kc 400cy modulated tone attenuation full up (max output). Adj # 17, 18, and 26 for max signal while adjusting the generator's output down so as not to overload the receiver.
Use an ac voltmeter across the voice coil to measure the output. Or a hi impedance analog voltmeter to measure the avc voltage for finding the peak output.
This completes the IF alignment.

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!
