I guess .1% wins this time. I found C61. It is a .05 instead of a .035 though. It was one of the black beauties and didn't have it's rating on it. It had the same marking bands as two other black beauties that were .05 though.
A few youtube searches on gassy tubes and I think this is what I have. The last two posts came in after I did the test so didn't have a chance to read the "don't do that" warning. The set was still only on for less than a minute.

This will help make it a little easier to see what the tube is doing. The video is of the new tube. The old tube does close to the same thing, just not nearly as much blue glow. I suppose #3 could be the charm.
