I wish I could do that but GSA10Gs and the likes don't allow that if you are driving Nixies, and the necessary circuitry around them is also designed for these high voltages. I might figure out a way to do it but that would be to go outside of the intended use by ETL and I am really not that eager to test it with these rare dekatrons. I've been fiddling around with a raised "ground" by supplying it with a few hundred volts for th etrigger tubes and such, but it does not change much in the total power needed on the 475V line, and it complicates the design more than I feel like doing. "Keep it simple" is what is needed here plus not deviating from the datasheets too much. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
