From the information you posted it seems the metal mesh grid in front of the segment must be powered to positive 5v and each segment to be lit must have positive 20-30v put to it. Where is the negative hooked up then? Also is there a heater in these tubes or what is the common long wire in the back of the tube? Thanks for any help you may give.</p> I just purchased some of these tubes on ebay and am trying to test light a segment.

A quick test:

  • Power the filament with a 5v
  • Power every other pin with a 20v PSU.

Each PSU (5 and 20v) share the same ground. (The negative for this tube is the filament)

I still am slightly confused, what pins on the VFD does the heater output in the schematic hook up to? Also the 20V is AC and the 5v is DC correct?</p> Jkx,
