I'm sure some of the many RCA experts will chime in, but in the meantime, that's a sweet set. It's tube-type, with a chassis that evolved from a long line of RCAs. Parts and help should be easy to find. Without knowing what's wrong with it (or if the CRT is any good), it's hard to say what it's worth. In the ballpark of "not much" though, huge consoles are not desirable in general.
You'll need to remove the cataract on the CRT if it's good, which is a pain in the ass but a pretty interesting process.
The stereo system in there is solid state, with some really powerful amplifiers - it'll have germanium output transistors making something like 300 "good old days" watts. It'll also have a pretty complex speaker system with a couple of 15" or 11"x14" ovals and if I recall correctly some horns. They sound pretty good.
Here is a brochure with your set in it from 1967, courtesy of drh4683:

Here is another thread here on VK about the same set:

Long story short, if you like the cabinet and the CRT isn't a dud, I'd be all over it.
