Commemorative Clock
Here is the Commemorative Nixie Tube Clock from year 2000. A total of thirty were assembled.
It is physically similar to the Original nixie clock. HV for nixie tube drive is supplied by an isolated flyback type power supply. This model was very popular and sold out quickly. A kit version of the circuit boards were offered as well.
The base is South American Walnut, finished in multiple coats of lacquer. The cover is composed of five Starfire Crystal panels. The crystal cover is incredible, with none of the common green glass tint.
The black knob at back is a rod magnet, stored in the base. The time is set using magnetically actuated reed switches.
