My typo.
The manual I found doesn't mention options. Perhaps yours is a later version.

You could use a sig-gen with AM modulation (1KHz) on 21.25 MHz to inject the signal at the output of the tuner. Trace it thorough the sound IF with a detector probe attached to a scope. You could not get the sound any further than the discriminator, however you could confirm the sound IF transformers were peaked correctly. You could check the 21.25MHz with a frequency counter if need be.
