> A higher supply voltage makes in the course of time more serious problems.
I don't think so. The efficiency is lower, of course, but the conditions on the tube are pretty much the same once it's on (the anode resistor drops more voltage, the tube's maintaining voltage and current are the same). The only difference to the tube is that it ionizes faster, as far as I can figure, and I don't see a damage mechanism there. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
