I  checked the operating specs on two of my QRO amps.  Not a KPA500.

2m-1500w PA using a MRF1K50 in class AB:
945w  1398w dc  67% eff  453w disp
1511w  1888w dc 80% eff 377w disp

2m-1200w PA using a MRFE6VP61K25H in class AB:
566w  1200w dc 47% eff 634w disp
1133w 1542w dc 73% eff 409w disp

less heat dissipated when running full power RF ouput.
Both are W6PQL amps.
