Decorative foil, under Philco chassis.
#4

It could be use to reduce hum as the regenerate detector operates at a very high gain. If you put your hand near the 77 tube you will notice an increase in hum. Good grounding around the detector/wiring is a must.

ps the radiation from would be a 460kc not at the frequency that the set is tune to. That was the problem back in the 1920's as the detector was tuned to the station on the bc band and would radiate over the broadcast signal to nearby receivers.

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!
