A ballast?
Ok, were just a little surprised to hear that it has one. I don't think that was common in an RCA of this vintage. There are some members here who work on sets for others. It would probably help if you posted your location.
Almost certainly it can be fixed.
There are probably some parts in it that could be showstoppers, but odds are it can be fixed.
It's old enough to have paper capacitors, so those should be replaced. Testing the crt would be a good thing to do.
