Try higher voltage but the same current (in other words, increase the anode voltage, and also increase the anode resistor). > If they out-gased, is there a method to detect this ? (I mean some method to > ionize the neon) Martin's suggestion of a plasma sphere or similar (fluorescent lamp tester, hand-held spark coil, etc.) is a good one too. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
