'67 AM Radio very quiet and static-y

[Dead Parrot]

If that is a mostly untouched original radio, my suspicion is some/most of the capacitors are shot or real far off original specs. One link on the subject: https://antiqueradio.org/recap.htm

Also, if something was inside the unit chewing things, it probably took a piss or dump inside. Neither does a circuit board and parts much good. It also may have chewed something else. If you have one, examine what you can with a magnifying glass or similar.
