Philco 84 now has a hum
#4

See if any wires touch or disconnected. If it developed it while still on the table this could be a contact issue. Turn it on its side, wiggle wires, etc.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
