This was on an instant start ballast. I went downstairs and noticed both tubes were out, so I figured it was a bad ballast. I shut the lights out for a while without investigating further or unplugging it. They next time I went downstairs I switched on the lights, and heard a pop and a flash and this happened to one of the tubes, but the other tube lit normally.

Yes it was, of the three cases of early 1970s mainlighters that my father saved, I have 14 left in service, one spare, and one I'm going to keep for my collection. They seem not to work well with the three instant start fixtures I have, they're underdriven and don't last long.
