To elaborate a bit more about what happens to the b7971 when the anode current-limiter kicks-in, I will need to study the I-V plots I generated from tube measurements. What will happen is that the anode current-limiter will effectively vary the voltage at the anode to maintain the total current at the limit.
If all segments had identical I-V characteristics, they would equally share the reduction in current imposed by the anode current-regulator. I think that the segment with the highest voltage-drop will "suffer" the most, followed by the segment with the next-highest voltage-drop. This is why I tried to keep all displayable characters at/below the max current limit. The intent of the anode current-limiter is for protection only. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
