  • @fulminationn no, normally filament voltage must be AC. But you can use DC for shorter tubes.

  • hi, i have a similar display. the filament is sensitive to polarity? ty for the help

  • @WaterpigMaste The dataheet says the voltages. Other tubes may need different voltages.

  • Ah… If the highest voltage in the circuit is 16v, why does the schematic show a 90v power supply?!
