About 1.5years ago, I built this really nice stereo vu-meter using IN-13 bargraph tubes. About two weeks ago, one of the tubes made a "tink" sound and the current control went away -- the tube stayed ignited, but the "bar" was stuck at the bottom. I noticed that the spacer at the far end of the tube was also suddenly free. I figured this was an unlikely failure, so I replaced the tube the spare stock. Unfortunately, one week later, the tube on the other channel did the exact same thing! I've attached pictures of my drive and power circuitry -- the signal conditioning circuitry is omitted, but I think it unlikely to be relevant. I figure something must be wrong with my circuit that is causing early death, but I'm not sure as to what. Ideas anyone?--You received this message because you are subscribed to the Google Groups "neonixie-l" group.
