There's no swamping resistor in the SB-200, there's tuned inputs I used one with my K2-100 until very recently (since replaced with a Transworld solid state KW amp) and it does behave linearly. The only caveat is that you need to use an interface between keying line of the SB200<> K2 ... no biggie. I can turn the power down to lower levels, and the amp still does it's thing, as a "linear" amp should!
