Ok, someone at SELEM handed me an old Laser Physics Reliant that came out of a night club, I think. The head was filthy. The path for the airflow was completely clogged. Took a good hour to get all the dust out of the thing. I really thought the tube would be cooked and probably wouldn't sustain discharge. So it kinda sat on the shelf while I got busy with other things (ILDA breakout, color delay, etc.). Welp, today, I was sitting around with nothing much else better to do, so I said what the hell, I'll give it a shot. To my amazement, this thing works great! 7 lines with a nice bright cyan and green line! Here is a pic of how bad the dust was, this was actually after I cleaned alot of it out! Getting the dust out of the clogged vents was a hassle! The last pic is of it actually working again. And here is a video link to me getting it started: http://video.google.com/videoplay?do...41020898&hl=en
