This paper introduces a new form of linear power amplifier for modulated radio-frequency waves. Plate circuit efficiencies of 60 to 65 per cent independent of modulation are obtained by means of the combined action of varying load distribution among the tubes and varying circuit impedance over the modulation cycle. The theory of operation is developed and detailed observations on the behavior of tubes……
