I have three 572B's in my Centaur and I can get 400 Watts out
on the 10 meter band only by tuning it to maximum out on both
the load and tune capacitors. The plate current is 500 mA at
1500 Volts. To get better linearity I reduce the drive to give
less power output. I can get 500 Watts out on the 20 meter band
but the current is more then 500 mA. The limit of the power supply
is 500 mA.
