DC input power is power indicated on plate voltage and
current meters. It is an average power. it would indicate
the sum of the two tones in respect to input power.
RF output power is PEP, which would be four times the single
tone or two times the average power in a two-tone test.
So we have:
1000W PEP input, and 470W PEP output. 47% efficiency
or we could view it:
500W average input and 235W average output 47% efficiency
Technology to build a very good PEP meter was available as
soon as man invented and learned how to work with the
capacitor, diode, resistor, and meter. My assumption is most
people working in electronics knew all four important things
long before 1960.
