IIRC that article had something in common with the one reprinted in Glass Audio that included the 81st harmonic.
It also mentioned intermodulations at the feedback node.
I've been repeating this stuff for years now so my Google searches are mostly dragging up quotes from me; not helping. I really should have bookmarked it when I saw it.
BTW if you don't know of Pete Millett's site its a good resource.
