The GS12C is a strange card in the Ericsson dekatron family: a base-12 selector with a maintenance base. This unusual base allows for connection of wire leads directly to the base of the tube, without any need for a socket. The duodecal sockets used on other ETL selector dekatrons will not work in their standard form on a tube like the GS12C, as a base-12 selector would require 14 pins to connect all of its cathodes.
