I recommend small series resistors for each anode; I'm using 100K SMT devices and with a 30uA load-current per tube that's a negligible 3V drop across the resistor. It allows you to measure tube-current, but be careful as it's 2kV.
Also helps reduce the zap if something shorts-out unexpectedly, such as when you are probing around and your hand slips ? I have an A/D converter under software control that measures the current thru the filament-transformer center-tap to GND. This allows you to measure all tubes (or individual ones if you shut off the others). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
