  • During 1935 there was no 6A8G, but the metal tube 6A8. The schematic may show the later model.

    The General Electric models A-82 and A-87 share the same schematic at Rider's 6-24 through 6-30 (Rating "V" Receivers) which show IF peak at 465 kc. They can have a 25 cycle (C) or 60 cycle mains transformer which came in two versions, one fix for 105-120 volts (A), the other for 105 to 250 volts with 4 tappings (V = Universal Transformer). The band A covers 140 - 410 kc (long waves), Broadcast band (B) covers 540 - 1750 kc, band C (Fishery, Police etc.) 1.75 - 6 mc and the Short wave band (D) 6 - 19.5 mc (foreign broadcasts). Electrical power output is undistorted 5 Watt or 7 Watt maximum. Push-Pull output with transformer.

    Stein "Cathedral & Tombstone Radios" lists 3 bands for this model.
