Top View Tubes

Top-view tubes

122P224

The 122P224 Nixie tube (or B5092A) was made by Burroughs of the United States, so this is a genuine branded Nixie tube. This tube is special because it has Krypton 85 added, which is a radioactive isotope of Krypton that emits alpha particles. These keep the Neon ionized and so help reduce the time it takes the tube to 'ignite', especially in dark conditions.

GR-1

The GR-1 is one of the first nixie tubes made by Rodan-Okaya (the other being the larger GR-2). You can see that the lettering on the tube is spelled Rodin, which is typical of the earlier tubes. This tube became the GR-201 and eventually the CD11.
