If I had that set, I'd immediately take a bunch of good digital photos and create a web page so that others could enjoy seeing a never-touched original.
As for restoring versus leaving it alone, I'd be tempted to do a Very Special restoration, restuffing all of the paper and electrolytic caps, keeping the original boxes for display, etc.
These sets were designed to be used, not stored in unopened boxes. Turning it on a few times a year to keep the controls limbered up wouldn't do any great harm. If you took photos of the restoration process, that would make interesting reading, too.
Or, you could sell it unrestored for a bundle and let the new owner deal with these hard questions
