No, Will should have said "for minimum distortion at 1 KW PEP
input and class B service at 2500 Volts, the maximum plate
current at single tone ..."
There is no indication that 1KW PEP class B produces more or
less distortion that say 1500 W PEP in class AB2 at 3000 V
on the plate. You cannot arbitrarily apply one set of conditions
to a completely different set of circumstances.
