Yup that's it. Pin 2 of the 1LN5 to the diode plate pin 4 of the 1LD5. It's not quite as effective as having a tuned circuit. The audio portion is being coupled though the small resonating cap inside the IF transformer. It too is about 100mmfd so it's not going to couple a bunch of audio.

Yup.

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!
