Oh it was just seconds ago when I understood what did you mean by the floating anode voltage. Right, that should happen, if one of cathodes is grounded, then literally any leakage current will cause 130Vish voltage on the anode to appear. However, this would mean that MMBTA92 have some serious leakage current issues if at Uce = 60V it leaks enough to cause visible glow. However, that still makes me wonder why do they leak only when other tube is conducting. There is a cathode grounded at all times and there is no voltage drop across the tube when no tube is conducting (probe internal resistance causes the voltage to be not floating, that's why on the graphs it looks like it's about 0V during dead time). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
