Well - voltage on the grid is a good thing but to double check the osc set the bandswitch for the bc band. Tune the dial to 1000kc. Use a transistor radio near the 7af7. Tune it to 1000kc + the IF frequency 455kc. 1455kc. If the LO is running you will hear a loud hum in the transistor radio. If the tuning isn't dead on on the Philco you may need to adjust it's frequency bit to hear the LO (local oscillator)

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.

Now I think I've got!
