At a guess, probably by Bob Carver, related to his ill fated magnetic amp.

I understand he actually sold a licence for it Yamaha, who then applied it in theri current series at the time, but for some reason Bob was very unhappy with it, legal minds clashed, and the deal broke down.

People sometimes will act different just to differentiate from the "crowd" that they live in. Some crave to show-off opposition to mainstream trends as their indentity, to state "I am special" (therefore better noticed from the rest of the group).
Any tool is good for that: tatoos, piercings, overpriced Apple products, LP collections, tubes amplifiers, NOS made with DAC's that are not in production anymore...

Ah, some here are goood at that kind of arguments. Will twist everything to their use... For example engineers for them are sometimes geinuses (when desing a DAC that is not in production anymore) or just deaf idiots (when specify the use of OS filters or OpAmps in final stage).
Well, to me, engineers, PhDs and so on are simply people, like everyone else. They stand or fall on heir own merits, just like everybody else.

Coming from a family chock full of PhDs, and about evenly divided into teachers and professors and bankers, I have had an outstanding opportunity to closely observe both Aside from outward appearances, the only difference I could claim to be true is that the banking half, plus my dad (he was the odd man out, a mechanical engineer), tended to be more practical when it came to the execution of a plan. But that's about it, the other differences I would attribute more to the underlaying basic profession than anything else. My uncle and aunt had PhDs in sociology and philosophy respectively, so it was to be expected that they would a bit slow on execution, but long and sometimes tedious in planning.

I think just about any family anywhere has a specific composition, nothing wrong or unusual about it.

Ah, that'll be me.
May i add an excessive scar memorabilia collection, a large number of kitchen utensils, and an substantial audio book & paper storage to the list.

You can't be serious, did you ever look at the service manual for a 7000 series TEK scope?

at 1st glance Malcom's DCDF paper ignores Bode's gain/phase integral constriants - their application to "debugging" non-physical claims for various "clever" feedback arrangements have been know since the late '50's

I've mentioned these control theory results, pointed to refs a few time now

Default Magnetic amps

D V V brought up magnetic amps .

I wanted to get one made for a project at work . The usually obliging transformer manufacturer ran a mile . Anyone ever heard one ?
