Jayce;
  U.S Radio and Television seems to have focused their efforts at designing and building table sets, since they were a smaller company they probably wanted to limit the amount of engineering they needed to a minimum rather then coming up with a completely different line for the console models. That would probably explain why these consoles stopped at a count of 8 tubes, that seems to have been the upper limit for most cathedral and tombstone sets at the time, other then from the bigger outfits like Philco or RCA/G.E. From what I can recall U.S Radio and T.V was actually a pioneer in the development of television, they did just tack that name on for marketing purposes, they were very much involved in mechanical TV in the early 1930s.
