Automatic tuning unit, called Seletronne by Sparks-Withington (Sparton). This was their first model with this feature, introduced in Summer 1937 at a price of $ 179.75. Aerial band matching transformers. Separate coils for each band. Tuning eye (not Viso-glo" anymore). Automatic frequency control - sold like this: "The SELECTRONNE contains no moving parts but the button switches....no motors...no complicated mechanisms. It is instantaneous and simple in operation as a door bell". Push-pull audio amplifier with triode output which drives the twelve inch electro-dynamic speaker with acoustic baffle. Alto-basso tone control. The Sparton model 1268 is covering standard broadcast 540 - 1750 kHz and two shortwave bands: 1750 - 6100 and 5900-18500 kc (kHz). Advertised: "Press one after the other of the six buttons and thus quickly sample the programs of the moment, from all six...without even a glance at the dial. There are no motors, no moving parts but the switch buttons. The tuning is expertly accurate. The response is full-toned. A touch of the band selector switch...the receiver instantly changes to an efficient, ultra-modern all wave radio model of surprising performance, ready to tune American and foreign broadcast and shortwave, Airplane, Police, Amateur and ship." By the way: The term "Selectronne" was already used in 1933 on a folder. But now (Nov. 11, 1937, "The spokesman review") could be told: "No Whiz! No Whine! No Whir!"
