Decorative foil, under Philco chassis.
#10

Conuctive foil is still being used, as a cheap alternative to a bottom chassis plate. I recently worked on a pretty new guitar amp, and it had foil where the bottom plate should have been, and the glue failed (you know the guitar amps have everything upside down,) so it was a real mess. Dead short output tube, bad diode, etc...

Thought about making a bottom with a piece of discarded
computer housing, but decided to just re-glue the original foil to the cabinet, and make sure the wiper was making contact. Been 4 months. Assumed working OK.,
