Looks reasonable so far. Apply a 455kc modulated signal to pin 2 of the 7B7. If you can hear that then apply the signal to pin 6 of the 7B7. Should be able to hear there too. Lastly apply signal to pin 3 of the 6J8. Again should be able to hear it there. Turn the generator output down so you can just barely hear it. Now adjust the trimmers at the top of the IF transformers for max signal at spkr.

I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
