Notes

First advertised in December 1922 Day Fan five-tube breadboard radio, sold as a kit by Ohio's Dayton Fan and Motor Company.  The radio consists of a Day Fan Vario-Coupler, a Day Fan Variable Condenser, Two Day Fan RF Amplification Units, and two AF amplification transformers (original to the receiver, but manfactured by Jefferson, not Day Fan).  The parts are mounted, along with tube sockets and rheostats, on a 24" slab of bakelite.  

According to historian Alan Douglas in Radio Manufacturers of the 1920's, the receiver's components were designed by Captain Orin Marvel of the McCook Field Radio Laboratory and -- like their Atwater Kent counterparts -- shipped out with factory plans for their assembly as breadboard radios and radio panels.  All of these sets were sold as kits.  Day Fan did not assemble any of them at the factory.
