With the signal generator adjust it so you have a modulated signal at full output at 470KC or for you modern guys 470KHZ. Take the output from the generator though a small cap, size doesn't matter here anything from 100pf to .1@ 600v is fine and connect it to the plate of the 6K7. But careful not to let the test lead touch anything as it will have HV on it when the set is on. If that stage (detector) is working you will hear the modulated tone from the generator in the speaker of the set with the volume set up a bit.
What is the cathode voltage on the 6K7? and is the filament lit?

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!
