And the output tank components. Besides which the coil taps are set to
give a certain plate load R and to get more power from drawing more
plate current with 872B the plate load R needs to be smaller. Yes, you
can reduce the loading C but as you do you also change the loaded Q and
the harmonic rejection of the output tank.
