The August 1916, issue of The Electrical Experimenter magazine was the first advertisement to offer a picture of the 1916 Moorhead Electron Relay. As noted in the advertisement, the tube was available with either a single filament or a double filament for $1.50 more.

At this time Moorhead was advertising under the name of Pacific Laboratories.
