If the "applied grid signal voltage swing" is AC voltage from the input to the amp, then I think I understand. If not I am still not able to put all the pieces together for an "aha" moment. If not that, what is causing the applied grid signal voltage swing?

Yes, the "applied grid signal voltage swing" for the first tube is the input signal to the amp.The "applied grid signal voltage swing" for the second tube in the amp is the output signal of the first tube and so on.
In other words, the "applied grid signal voltage swing" is the input signal to the grid of the tube and the graph is describing what happens to the tube (in terms of current and voltage changes in the tube) because of that signal being applied to the grid of that tube.

Hurrah! By Jove I think I've got it! At least this one tiny little piece. All this is definitely going in the note book. Thanks for taking the time to explain it, Tre', it really helped!

There is a simple formula, starting at the bottom of page 2, that will give an approximation of the 2nd HD based on how much one half of the output wave form differs from the other half of the output wave form in terms of amplitude.
This is an article written by Norman Chowhurst.

Thanks Tre - I will save that with my others. I own a few relevant texts and articles but not read all of them extensively; of those I have read it has been a while...
What I liked about your contribution was the discussion (or Q and A) and relevant information provided in a way that was easily digestible (and without ego). Great stuff.
Cheers,
91.

I vote for a weekly post called "Tre's Tips" posted in the same style!
