The tube was a medium gain twin-triode with independent cathodes. According to "Popular Science" Oct 1938 this was a new design in 1938. It is listed in the 1937 Ratheon Receiving tube manual.

While the Atanasoff-Berry Computer (ABC) runs successfully, the reconstructed device clearly should not repeatedly be used for live demonstrations that would lead to wear and tear. Soon after the reconstruction was completed, this video was made to show how the computer could solve a complete problem from beginning to end.
