RE: Read his thesis why don't you?

I enjoy all of Keith Howard's writings. IIRC, there is not a big difference between any of the patterns and he struggled to order them.
There is a utility that allows you to add a desired amount of distortion see link. If I want to add a lot of low order distortion I simply play a record.
As to Cheever, I obtained Olsen's text book referenced by DC and it contains the same graph but Olsen attributes it to someone else. I obtained that paper and though relevant it is not the source for that graph so more searching required. What I can say is that Cheever misinterprets that graph - it shows the level of a fundamental at which it's harmonics are detectable. They are not the absolute level of the harmonics as the author suggests! The next graph is probably the most important, similar data attributed to Olsen but that must come from a different book. I will seek it out to find how the testing was done.
