Reducing the power output without changing the plate voltage
will result in a miss-tuned condition. If the pi-network is
tuned for full output and the drive reduced (power adjusted).
If the output is retuned and the lower drive level, the plate
load impedance will be incorrect for the design of the pi-
network and the pi-network will need to be detuned (run at
a higher Q).
Either condition is a miss-tuning of the amplifier.
