fixing am radio?

Rani,

Thanks for the schematic it brings back memories. The 1968 the schematic suggests a vacuum tube design was replaced with transistors. More modern designs replaced the audio coupling transformers by direct coupling transistors using emitter follower circuits.

Chrysler was one of the first with all transistor radios in 1955, my dad had one. It failed in the early 60's my uncle (a ham radio operator), repaired it with transistors taken from a pocket transistor radio. Watching my uncle do that, is what gave me the start in electronics.

Here is a 1955 Chrysler radio sales video.
