Okay,
Please explain:

Now you say maintain dip with load capacitor. I am indeed Polish, BUT
you seem too JUST have contradicted what you said.

When I say "maintain the dip" I mean I recheck the dip changing the load

I must be missing something in your words Bob (DGN). If, after operating
at some plate current and RF output using a PI network, and now you want
to reduce output, why would reducing the loading and re-dipping the plate
capacitor (to return to resonance), become "non-resonant" unless the
words that Bob (MYJ) used, "maintain the dip" means that he doesn't
re-dip the final after a loading control change. Since the beginning of
(my) time, the last thing I always do in a tune up procedure is to dip,
or check the dip, of the final.

You're using a PI network, NOT a link tuned system. If you reduce
loading, AND maintain plate dip, You will indeed reduse output AND
go
NON-RESONANT.
This opens a whole other can of worms.

It's the same as reducing the coupling on a link coupled final.
