Remember that the old AM equipment performance rules required you to be
+/-2dB from 100Hz to 5 kHz. Measurements were to be from 50Hz to 7.5kHz.
That old vacuum tube equipment (consoles, transmitters, etc.) was
typically flat down to 30Hz. A lot of the later stuff would roll off at
50Hz. You stack several of those items together and you could not reach
the 100Hz requirement. That old "big iron" stuff was pretty good.

Harold the old AM rules required that you go down to 30 Hz.  Later on amended 
to 50 Hz.  I know because when I did the specified 30 Hz. the 60 Hz. 
flourscent lights would beat with the RF.
