I've got it home now and got into it, it's quite a little set. There are 19 tubes including the CRT (17DKP4). I powered it up and the screen lit up and I could see a snowy picture without an antenna. One of the filter cans started to heat up so I shut it down. The CRT took awhile to brighten up and it may be a little weak but it doesn't have a britener on it. Should be great for watching old B&W movies on when I get it dependable. Now I'm going to have to rebuild a UHF converter for it.
