Sometimes I've gotten TVs of that vintage that still worked well, or at least well enough to tell me that the important parts were in good condition. I'd still go thru the set and replace any wax paper caps, as I knew that the effort wouldn't be possibly wasted if was a set I was restoring had a fatal flaw. Do one cap at a time. Also the electrolytics too. You'll want that set to be working when you get to be as old as most of us here.
And Merry Xmas.
