Can anyone explain why does too low current damage nixies? If the current is too hight, the sputtering will spread and cause cathode poisoning. But why does this happen with lower current = lower sputtering. I am asking because I want to add an automatic brightness feature in my clock using PWM. I am worried that too low brightness (low RMS current) at night might reduce tube's life. Or does current rule count only in constantly driven tubes..
