  • The 782-L Prest-O-Matic (Prestomatic) has push-button tuning for 6 stations. 8-inch dynamic speaker, Walnut Cabinet. Two bands: 16-53 and 173-555 meters.

    See also the two other models for the season 1937/38 according to "Radio Today", November 1937, page 66: 782-1 and 762-L.

    See the full range for 1937/38 according to a folder with Challenger 5, Challenger 5 L.W., Prest-O-Matic 782L, 782-1, 782T, Challenger 1, Challenger 2, Challenger 3, Challenger 3C and model 762L Prestomatic plus the Phonograph-Combinations: 782-P8 with Prest-o-matic instantaneous tuning and 307-P8, 803-P8 and the models where a long wave band for 835-2050 meters can be installed: 309-P8, 903-P8, 3012-P8 and 1203-P8. According to Stein-Books you can find the same cabinets and chassis for Garod - at least from several of above models. There seems also to be a model 309-L with probably 7 tubes besides the 309-P8 with 9 tubes and phonograph.
