  • Notes
  • The General Electric models A-52 and A-55 share the same schematic at Rider's (1st Jan. 1936) 7-1 through 7-3 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). The Broadcast band covers 540 - 1720 kc and the Short wave band 2.3 - 7 mc.
