I wonder if there are any 50KW AM vacuum tube transmitters in use anymore? I
read the excellent article about the Harris 50KW solid state xmtr that WLW
uses, pretty neat. In the sixties, what would be the plate voltage and
current for a PA running 50KW in AM? I'm sure they would use three phase
input power, but how much filter capacitance would be needed to insure a
quiet carrier? Always wanted to know.
