Happy Birthday to your mom! Later this afternoon I'm headed out to my granddaughter's birthday party she's 4.
Good seem like you got the output stage sorted. Does you chassis have two #41 tubes?
If you measure the voltage on pin 5 of the 6a7 as you tune the dial is there a point where the voltage drops off sharply? If so you may have a bend plate on the oscillator side of the tuning cap.
Would go ahead and align the IF stage to get that out of the way as a trouble source. If it's misaligned that can cause poor sensitivity (no stations).
Just for grins try connecting your ant to the grid cap on the 6a7. This will bypass the rf amp stage, if it's not working this can cause poor sensitivity too.

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!
