I discovered that the solder connections on a capacitor were bad.
Apparently, the solder iron overheated the contacts on the board
causing plastic on the board to melt onto the contact. I made a
temporary fix by soldering the capacitor directly to the resistors it
is connecting. I'm picking up radio stations now, but there is a loud
squeal. Maybe the timer is oscillating? Is there anything that can
clean melted plastic off a contact?
