It's a 12LP4A, NVC branded (National Video Corp). Tube looks good, no burn in. I have to find out the hard way whether it's bad or good, since I don't yet own a CRT tester.
I went out and purchased the set in Wisconsin today, since it was only a 20 minute drive from my house.
It's going to be a work in progress. It powers on, no raster, but it gets sound and gets signal with loud and clear audio, so all that is working. I probed the anode and it's only producing about 2kV, so it needs caps, and some adjustments.
