The BG08220-K, manufactured by Burroughs, is a glow transfer counting display that defies all conventions of dekatron construction. The most obvious difference between the BG08220-K and other dekatron tubes is that the BG08220-K is not even a "tube"; Burroughs constructed the device using a glass sandwich system similar to the construction style used in their Panaplex displays. The BG08220-K is a base-24 device, the only base-24 counting tube such known, and the non-guide cathode positions are elongated and easily seen through the front of the device. The tube also has four guides, double the amount used in a standard dekatron, and is filled with neon gas for easily visibility. The BG08220-K is designed primarily for display instead of counting, and has only a single output cathode located at the 6-o'clock position.

Unlike nearly every other dekatron ever made, the BG08220-K has four guide cathode groups, and only a single output cathode.
