Hi Derek and welcome,
I would break out the signal generator and set it up to produce a modulated 455KC signal. Connect the output of the generator to terminal strip on the back of the chassis terminals 2 (signal side of the generator) and 3 (to the gnd side of the generator). If the IF and det stages are working you should hear If you the modulating tone. At this point you can adjust #27a, 27B and 30. If you are using a old 50's service grade generator double check the calibration . Turn the set on in the dark and make sure that all the tube are lit, the loctals can be a little hard to see into.

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!
