[Elecraft] KPA500 new owner questions.......

[BRUCE WW8II]

I agree with Rick just keep the drive power to the minimum needed to get
the 500 watts out.  Over driving will do nothing but distort the signal and
most likely eventually damage the amp. I use 18 to 20 watts to get 500 out
on 160 mtrs  and a bit more to get same results on the higher bands.
