You don't need a "Nixie tester". All you need is current-limited high voltage. In the US, a 100K resistor in series with 120-150 Vac (use an isolation transformer; do not connect directly to the mains!) should light one or two digits at a time.
Are you sure they are new? Can yo see any longitudinal scratches on the pins? This would be evidence of insertion into sockets. To my eyes, it looks like the pins are not true. That could be evidence of stress that could have broken the glass-to-metal seal and allowed the neon t leak out. The conventional wisdom is that sockets should have floating pins that do not stress the pins (socket pins not rigidly soldered to the pc board). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
