  • Notes
  • The International Radio Corporation model "Kadette" or "K" 1149 has 8 receiving tubes incl. rectifier plus 200R and 250R as ballast tubes and the 320R4 as a regulator tube. We don't count such tubes but in the advertisements for Kadette you will find the wording for 11 tubes. Model 1149 ha a push-pull AF output stage. The Kadette models 1129 and 1149 share the same schematic (Int. R.C. Rider's 9-7), the one on the same page for model 1159 is very similar. The loudspeaker is a model D-65 with 600 Ohms. See also ads in the monthly journal "Radio Retailing" for August and September 1937 (pictures attached).
