x-ray tubes

We have all heard the stories of mercury tubes and radiation and here is another take on the subject.  There is a guy named "kenpeter" over on DIYaudio who started a very cool thread using X-rays to look at grid alignment of tubes.  Since most of the talk centered around multi-grid output tubes, I just sit back and enjoy the pictures.  (both pictures borrowed from the thread and belong to kenpeter)
