Hi Group. I bought 10 pcs. of SP-352 on eBay, mounted on some NOS PCB's, very nice indeed.
http://kortlink.dk/ebay/89s6 Markings on the PCB are: ASSY. T13372-G and a sticker on the back says: 41707370 USAI 5294. Googling the numbers come up with a site selling parts with this listed: "G-T13372-G1 Replaces Gilbarco PPU Display $81.25" Apparently, Gilbarco makes Gas-pumps for Gas-stations etc. The Panaplex'es are driven with some Q10584-01 chips, that i unfortunately has been unable to find a datasheet for :-( It looks if they are simple transistor array for switching the segments with TTL 5 volts signal. The board has a wiring loom with 4 wires, which is the power supply for the panaplex'es as well as a heater!. There is a custom, bakelite "socket" like assembly that the panaplex'es sit ontop, which has a heater wire (golden color, about 36 cm. long in total). The board is fed with 170 volts for the Panaplex, and 24 volts for the heater - the 5 volts for the logic is supplied via the 20 pins IDC- connector. Some images of the beast: http://kortlink.dk/zapro/89s9 Now the question - why a heater ? I thought that Plasma displays and Nixies was pretty unaffected by low temperature, but maybe not ? Just wanted to share my "find" with your guys :-) Regards, // Per. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
