Good evening, Bill.

I'm sure there have been but I was not able to find any that were directly on-point from the last several months or so (much older than that, and information sometimes tends to get obsolete, and anyway it doesn't hurt to re-raise the question occasionally, in case new information is available).

That is often true.  I feed the outputs of both the exciter and the amp thru a Kenwood SM-220 scope and watch the trap pattern while speaking.  I can tell pretty accurately when the amp is going out of linearity... tends to start happening above about 600 watts peak or so.
