With the NE-2, I needed to characterize them and sort them, and in each ring counter only use bulbs with matching striking and maintaining voltages. With the MTX90, I only quickly tested them to avoid out some outliers and a very few that didn't work at all, the rest worked fine in the ring counters without further matching. There's a large spread of striking voltage among them, but the difference with the maintaining voltage is larger still. With the trigger electrode not connectected, the striking voltage is (far) above 200 V, and the maintaining voltage around 60 V. Compare that to about 80 V and about 60 V for the NE-2s I used back then. But only time will tell if and how this changes with aging...
