I replaced a couple of bad tubes and ran it up to about 100 volts on the variac (hey -- do what I say, not what I do
), when what to my wondering eyes should appear, but a bright green glow in the CRT neck.
What the heck? The glow comes from what looks like some kind of schmutz on the tube element.
This is without using the brightener (or should I say Britener?).
At roughly 100V the TV produces fine audio, which is mildly encouraging.
The ion trap magnet was originally far back against the tube base. I slid it forward out of curiosity and found that it has a slight effect on the green glow.
Never having seen a green glow outside of a magic eye tube -- this looks exactly the same shade, by the way -- I am most curious.
