  • Notes
  • The "1921-1932 Radio Collector's guide" by Morgan E. McMahon, starts on page 55 with "De Forest Radio Co." in 1919 (for the fifteen Panel). On page 56 there can be found two models D12 for 1924. They only differ in price - and for both are given 4 tubes which is wrong. There are 4 tubes in a row plus one quite separate. Two dials (primary tuning control knobs).
