AM/FM radio and wire identification

Bendix radio. I have the factory service manual for the early series. Repaired many over the years and have one being shipped to me now for repair.
These are AM radios that have kludge FM as a quick and dirty after thought. FM performance is far from good. I actually hate working on them as the FM PCB and tuner are a bear to take out and repair.
Not sure when the audio amplifier transistors changed from TO3 to TO220, but each are robust and reliable.
