Lot of 26 pcs Nixie tubes by Siemens on control board. Tubes are nor tested or guaranteed but based on my experience I think they all are perfect functional. If someone is interested on minimum 6 pcs on a multiplexed board and full control kit for a total of 220 Eur, please let me know. But I prefer to sell all 26 pcs at once. For other, please contact me for the cost.
