>What should I hear out of the speaker?
Depends. If the have the modulation turned off you won't hear much at all. With it on you should hear a 400cy tone.
I would leave the grid cap on the 6A7 and connect the generator to it. Keep the generator's output turned down so you can just hear the tone. As you adjust the IF trimmers for the loudest tone in the spkr.
What are you using for your service info?? Please post link to it as the Rider's is for an early model.

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!
