  • Notes
  • The radio model Gamble-Skogmo 6D, a farm radio, was made by Wells-Gardner as model 6D. The model, 6D, is stamped into the chassis. Wells-Gardner was a contract manufacturer, sometimes for different clients, as here for Gamble Skogmo, Inc. which called the model also as 6D. The schematic is found at Rider's Vol. 10, page Gamble 10-1 and 10-2 and the same for Wells in Vol. 7. The tube 43 is the driver and the double triode 6A6 is the push-pull power output tube. This radio, with most probably a slightly different cabinet, was also sold by Lafayette as as model B-12 32 Volt Receiver.
