Most of the amplifiers of that day did not have the power supply
and/or tube capacity to supply even a 6 dB peak to average ratio.
In many cases the amplifier was doing the "speech processing" with
all of the attendant splatter and distortion.

They were also not tuned properly ... most tuned for 1 KW input with
carrier not realizing that would cause peak clipping when driven
above that level. An amplifier needs to be tuned (and loaded) for
the peak output to be linear ...
