Well it's not your average 5tube ac/dc model!!!
I would start by using your sg set up to generate a 470kc signal w/modulation. Go around to the grid caps of the IF amps (6K7's) and see if it will pass a signal. Have the fidelity/tone control tuned to treble this will give you the widest IF bandpass. Doesn't matter where the main tuning is set.
When troubleshoot ing the RF deck an octal tube extender can be a very handy thing to have. It allows you to access the tube's connections from the top of the chassis rather than trying to dig around on the under side.

You can make one if you have an old tube base and a socket.

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!
