You make a DL for the frequency that presents the designed load Z and
can handle the power. Then you make as sure as possible that
everything SHOULD work according to plan. Then you work out a kill
switch that will shut down the show if there are any fireworks. Then
you cross your fingers and fire everything up and see what happens
with your hand on the kill switch.
A lot about megawatts is the same as kilowatts; just different
cooling, and bigger parts, and bigger numbers.
