In 1921 Arthur Atwater Kent produced his first radio components, selling them do-it-yourself kits consisting of "breadboards" that could be assembled by early radio enthusiasts. In 1923 his firm started producing complete radio sets, using a facility on Stenton Avenue.
October 1930 "The Crosley Broadcaster" featured on page 15 the Crosley Screen Grid Receiver 26-H and the new Crosley power speaker in metal case to match. The model 26-H has one dial (primary tuning control knob). This battery radio has the same schematic as the other models 26, like the console 26-J Crony or 26-K Partner.
