The tube has 8 grid 16 segment (with colon and dot). Grid voltage 14V, Segment voltage 16V, filament 3V DC.Schematic:http://www.hpfriedrichs.com/images-rr/vfd/lightcircuit.jpgEnjoy.

@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?!
