Thanks Nick, Greg! a fully lit lamp takes 4.5 milliamps (I just measured it). This is also about what the data sheets say. What you describe reminds me of when I wired my tubes in backwards, they took 20+ma and didn't last very long. As for retreating, If you are not going full on or full off, you need to ramp the voltage up and down a bit slowly, that is why you see the spiral you do when the clock changes. The IN-9, which is a two terminal tube, needs an even slower ramp to keep the line from going goofy. My clock will work with either tube. There is a jumper that the code reads to determine which tube is being used.
