I have several of these available. They look to be very clean and test well at 100W out with 1-4W input. I tried them down to 440MHz and there was no change in power output. Crescend makes these in a variety of input power ranges but the only change is the value of the attenuator at the input stage of the amp. In the past I have ordered different value attenuators from Crescend and changed them to 10W input or 25W, etc. $400 each including shipping to lower 48.
