Would break out the signal generator and align the IF stage. Looks from the schematic that this set is inductively tuned. This mean instead of a tuning capacitor it move three slugs in or out of the rf coils as you tune the dial. Check to see that the slugs are moving properly and that they are not broken. If any are stuck or broken the set won't tune properly and have poor sensitivity. Then align the rf sections.

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.

Now I think I've got!
