This auction is for two Sperry SP-429-09 vacuum fluorescent displays (VFDs) or "planar plasma displays" in very good condition. A datasheet is included. Both displays are mounted in sockets with solder tabs. It appears (from the datasheet) that these displays require nominally 180VDC and produce an orange ("neon glow") color. These displays are untested and as a result are sold as-is. They appear to be unused (but I can't say that for certain).I prefer I ship via USPS Priority Mail.
