Sure why not! Connect the output of the SG to the grid cap of the 77 mixer tube. Set the SG up to produce a modulated signal at 460kc. This will tell us if the IF stage is working. If all is well you will hear a 400cy tone in the spkr. Obtw What happens when you adj the sensitivity control on the back?? With it turned up it should squeal ( go in to oscillation)

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!
