Very nice find! Unfortunately those 19AP4's are very problematic after all these years , hard to find a strong one these days. I would suspect your set originally came with a DuMont CRT, after all they did make their own tubes.
It's kind of hard to make out, but it looks like the RCA CRT has the code date stamped on the locating key. Generally means that it is a replacement.
