Jerry and all,

OTOH, I would be quite uncomfortable purchasing a modern SS amplifier 
that did not implement protection from excessive SWR without depending 
on the exciter to throttle back the power.

To my mind, depending on some external device (the exciter) to protect 
the amp is a recipe for failure and represents faulty design decisions 
from the amplifier designers.
