This one is more focused on history than on a particular bit of theory, but what a treasure trove of history there is in this 1976 flick! Walter Brattain (transistor inventor) reading from his lab notebook! Edison's lab assistant describing the first recording of human speech! Marconi's daughter! Alexander Graham Bell's granddaughter. You guys will like this one. Three cheers for AT&T!

From looking at the schematic, and considering that the radio is drifting
slowly over time, I would suspect C4 and R4.

I like the part when the guy in the lab coat shouted, "It's alive! IT'S ALIVE!!!
