[Vintage-Radio] Radio Craftsmen and 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 Radio
Craftsmen and Hallicrafters:

Radio Craftsmen C550 amplifier, C400 amplifier, 800 AM/FM tuner/preamp, 900
FM tuner

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

I've already got the SAMS that are available for these.  I'm looking for the
original manufacturers literature.
Any assistance is very much appreciated.  Thanks.

Regards,

Paul DeFayette
