What to do with old set of audio equipment?

Hi everyone - 50+ years ago my father put together a nice audio system in a custom cabinet.   I'm now refinishing the cabinet and I'm wondering what I should do with the equipment?    It has a Scott Model 222C amplifier, a Garrard Auto Turntable - Type A Mark II and a Viking reel-to-reel system.   I also have a nice set of the original documents as well (not sure how they held up so well!)

I'm sure the equipment needs work - the amp does power up and the tubes all seem to light up, but I have no idea if it will play as it is.  The turntable powers up but I'm sure it needs parts to fix it up.   I haven't done anything with the Viking equipment.   It was all stored in a basement for the past 30 years.

Is there somewhere I can take them to get them refurbished?   I'm thinking the best option may be to sell it to a shop or someone who refinishes them but I'm looking for ideas.   

Thanks for your help.
