Data sheet shows max Plate V=2250 and max Plate ma=600. Typical AB2 use
is Plate V=2200 and Plate ma=500
Typical Usage 2200 X .5 = 1100 watts in at 65% efficiency = 715 watts
Max Usage 2250 x .6 = 1350 watts in at 65 % efficiency = 877 watts out
Ran one on 2m and could get abt 900 watts out key down with Plate V of
abt 2300 vdc.
