1967 RCA stereo/tv with CTC21AC chassis

[amglow]

I’ve worked on old audio equipment before, but never a television. Lately, i’ve been looking into the possibility of obtaining an older color tv to wrap my head around and give it a go. There haven’t been too many prospects in my area. Today, however, I found this beautiful RCA stereo/ tv. I was told in an RCA group that this is the New Vista “Caulfield” model HH-856 from 1967, with the CTC21AC tv chassis.

I would like the get the opinion of the experts here as to the quality and capabilities of this tv chassis. Is it worth pursuing? Is it a solid peformer once restored, or does it have any known issues? Is it a tube or solid state chassis? Thanks in advance for any information you can provide.
