[Hallicrafters] Hallicrafters literature request

[Paul DeFayette]

Good morning,

I am looking to purchase good copies of sales literature, owners manuals,
and service manuals for the following mid century hi-fi items from
Hallicrafters:

Hallicrafters A84 amplifier, ST-83 AM/FM tuner/preamp

I'm looking for the original manufacturers literature.  Has anyone heard of,
or seen, these items before?  I didn't know Hallicrafters got that heavy
into hi-fi until I saw these.  Very nice, sharp looking, chrome chassis.
Looks very similar to Radio Craftsmen of the same period.  Any assistance is
very much appreciated.  Thanks.

Regards,

Paul DeFayette
