I have an old true dual beam Philips scope tube, but i have given ut trying to get some kind of picture on it. I do not have suitable power supplies to do it, and the main problem is of course the 3kV 2nd anode voltage. I have also tried to test some old indicator/"magic eye" tubes, but again the only power supplies i have that may give suitable voltages are so powerful that a short circuit would be like a small explosion, and i would need rectifyers and probably some smoothing caps. If i understand right, there is one pin to "light" the beam and another one to control it? Does someone have a simple circuit to test a 6U5 indicator tube?
