Hi,
My KPA1500 just started needing a lot more drive (2X) to get 'normal'
output. I normally need 25-30 watts drive to get ~1k out. Now I need
about 60W. I get two kinds of alarms, depending on how I test the
situation, either a red "Gain Low' or a yellow 'Input Pwr'. If I drive
with a steady 10w, I get a 'Gain Low'. On cw, Just before cutting out,
I can drive the amp with ~65w, get ~600w out, then get 'InputPwr"
followed by Gain Low' and the amp cuts out.
Time to go back to the factory?
Tnx, Frank W2YK
