[Boatanchors] 120 - 240vac and output

Yes, but you don't do that, either legally or practically.  And my analysis 
was an engineering one, assuming that the supply wiring was adequate to the 
task.  You are assuming the opposite.  That the wiring is inadequate.  A 10% drop 
in supply voltage with load due to drop in the supply wiring is obviously an 
overload.  Anyone who would design such a system should be fired.  You don't 
design 120 volt systems using the same load figures as for 240 volt ones.  Not 
if you want to keep your job, or keep your house from burning.

As I said before, any transmitter or amplifier designed to run on 120/240 
that won't deliver the same power on either is poorly designed.
