1pcs IN-14 nixie tube Gazotron factory made in USSR, tested, used

Description

Glow discharge indicator to work as a visual digital indicator of electrical signals. Cathodes are in the form of Arabic numerals (0 to 9) and two commas. The height of the numbers is 18 mm. Indication is made through a lateral surface of a cylinder. Design – glass, miniature. Weight 20 g. Electrode leads: 1 – anode; 2 – a comma sign; 3 – number 1; 4 – number 2; 5 – number 3; 6 – number 4; 7 – number 5; 8 – number 6; 9-digit 7; 10 – number 8; 11 – number 9; 12 – digit 0; 13 – a comma.
