Pete,
The specific reference he provided was for the DX-60.
The reduction in loading is followed by checking the grid drive NOT
dipping the plate.
I have the complete condensed copy of the manual from Heath which
includes the HG-10.
I agree with check the dip of the final.
Hence my comments, and also my comment that Novices did NOT have AM or
Voice privileges.

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.

Bob,
I'm NOT Pete. He may feel insulted. LOL
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.

No Pete,
I am saying to reduce the load capacitor and maintain the dip on
the plate
capacitor.
It's the same as reducing the coupling on a link coupled final.
