I'm pretty sure it's not the board. I've swapped around all the logic chips in that circuit and all that's left is the cathode drive transistors. I'll desolder the tube when I get a chance and apply voltage to it. Someone else suggested running the HV between the defective cathodes, but could that make the problem worse? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
