Something I'd look for would be a short between plates in one (or more) of the tuning gangs as the tuning cap is meshed closed.

Something else to try is tune to a station down at the low end. Then try touching the stators one by one on the tuning cap. If volume increases you've got a tracking issue with the rf amps.
