Hello- I've watched this thread with great enjoyment and also admiration for your skilled work... I have no idea how much of a risk you run with a nominal hv of 30kv but I doubt it's emitting significant x-radiation. It goes without saying that the shields around the rectifier should remain in place at all times. Remember the 70s sets like Zenith that would knock the necks off the tube bell, they were supposedly spiking to about 40kV for that to happen. And of course G-E in the later 60s.
If all seems well, it probably is. Smart to check HO current to make sure.
Nice piece of TV history!
