Just one question; How would one of these devices preform if it was subjected to one millisecond spikes twice it's maximum drive rating day in and day out? You can do this with many, not all tube amps but I wouldn't even think of trying this with any transistor based amplifier. I'm not by any means against solid state amplifiers they have advantages. Amateur amplifiers have to be engineered to work with any radio good bad or indifferent. That is cheap but I wouldn't put that behind my IC-756, not with that radio generating 125+ watt spikes on transmit.
