If the 1st and 2nd audio stage is working, you should be able to inject an audio signal by using your finger. You should get a louder hum than the audio level. Either that, or use a signal source, such as an FM tuner etc. Just touch the center pin of the output cable to the center lug of the volume control pot.
That radio seems to use a different type of AVC circuit, than many of the other sets of the day.
