• Anotaciones
• December 7, 1921, Powel Crosley filed a patent for his porcelain tube socket. Al least in February 1922 it was offered in ads like in "Radio News" for 60 cents, together with the "New Crosley Variable Condenser", Crosley Cabinets, The "Two Step Amplifier", Vario-Couplers, Harco Radio Receiver, Harko Senior Radio Receiver and Detetor units. Then it was under Crosley Mfg. Co., Radio Dept. R-7, Cininnati, Ohio. Click here for a summary of early Crosley and history.
  See also about the patent from December 7, 1921 for the V-T socket which therefore must have been simpler in 1921. This can be an important difference when looking at a really very old crosley model Harko Senior.
