I remember we had one of these TVs when I was very young. It was probably ~15 years old, sat in the basement and never worked. Eventually we gave it to the furnace repairman. I never saw it working.
The cabinet style matches the one we had. There are RA-112's with nicer, less "plain" cabinets. I almost would have rather had gotten a similar RA-113 just because the 17", rectangular CRTs are still available. This one has a round, metal/glass 19AP4. The installed tube is a bit weak, but it came with a stronger one. There are no substitutes for it and currently nobody rebuilds them.
You're right, I think this could be a lot more challenging than a radio. A friend has an 8XP4 I can use to bring up and debug the video. Maybe I'll look for a cheap sweep generator at Kutztown next week. I broke down and bought a digital scope recently. I didn't get it specifically for TV debug, but it could be useful.

Can't think of anything witty.
