  • Notes

  • Belmont in Chicago manufactured this and many other models for Goodyear. And Belmont manufactured also for other brands like Crusader, Classique, Freshman,Imperial, Starck Classique, Skyrover, Truetone and Wings. This same model 777 was offered at least as Goodyear Wings and as Skyrover.

    The Goodyear Wings model 777 was built 1935 for season 1935/36. 3 different chassis have been used for models 777, Series A, Series B and Series C. Richard Arnold tells in ARC: "The tube line up for Series A is as follows: 2-6D6s, 1-6C6, 1-75, 1-76, 1-42, and 1-80; for Series B: 2-6D6, 1-6C6, 1-76, 1-6B7, 1-42, and 1-80; and for Series C: 2-metal 6K7s, 1-6C6, 1-metal 6C5, 1-6B7, 1-42, and 1-80. The chassis layout for the series C is the same as the series B, except that the 6K7 tubes are used in lieu of the 6D6s and the 6C5 tube replaces the 76 tube. The IF frequency is 465 Kc.

    Frequency ranges varied from set to set. All versions of the Model 777 have three bands broadcast, intermediate and shortwave. The broadcast bands are the following: Series A, 525-1700 kilocycles; Series B, 525-1600 kilocycles; and Series C, 535-1725 kilocycles." Speaker 6,8 or 10 inch.
