The Anod OG-4 is a fairly standard 2KHz double pulse counter dekatron with a neon fill gas. The OG-7 is internally identical to the OG-4, but has a gas mixture resembling helium-hydrogen and a respectable counting speed of 50KHz. The OG-9 is a computer counter variant of the OG-4 with multiple output cathodes. All devices in this series were manufactured in both metal and phenolic base variants.
