An update on the set: I cranked it up on a variac over the course of a couple hours and it seems to be working great.
Sadly, unable to pick up any analog stations, and lacking anything that outputs analog video at RF, all I was able to display was snow. (it doesn't have an F-connector, so I am not exactly sure how I would input it anyway, except to maybe strap an antenna to the video source somehow). I am considering making some kind of frequency modulated transmitter and using an RCA output as the modulation signal so as to get a video signal to the antenna, but perhaps there is some easier solution I am missing here?
