This guy has not asked me or Mr Jung for permission to make money off our work.
Please note that if you have issues with this PCB you're on your own - the original boards, sold by diyaudio have been tested and tuned over several generations and are guaranteed to provide the very high performance these regulators are known for and which are confirmed by Jack Walton's measurements here (scroll down to Color graphs for Jack Walton's regulator article in Vol 4). With this amateur boards, which is are one generation behind anyway, you take your chances.
Also, note that when you buy the diyaudio boards, neither myself nor Mr. Jung get a penny from it - proceeds go to the support of your diyaudio forum, rather than to someone who apparenly has no concept of honesty or decency. You decide where you dollar is better spend.

circuits not protected by current, active patents are public domain, "prior art"
no one can claim to control their use, ask for money, restrict them to nonprofit/diy only
once published and not patented within 1 year (US) they are public "property" - any asserting control are the ones trying to steal from the commons
unpatented ideas, patented ideas after expiration are meant to be copied, used improved "to promote the advancement of the useful arts"
people may be able to control their names use in advertising, however we do have a long tradition of using personal names in association with circuits - Lin, Bailey amp topology, Locanthi "T" output, Widlar current mirror, Gilbert multiplier cell...
exact copy of "art" - including circuit diagrams, pcb artwork are controlled by copyright - but only exact/mechanical/digital copying - redraw, re layout and your art is yours to copyright

jcx, you obviously feel strongly about this - going back to find 10 year old posts (or maybe you're the only one here understanding the search function ;-).
I'm not claiming 'ownership' of the Jung/Didden superreg, I know the rules for such things and I also stand on he shoulders of giants.
But I made this PCB for diyaudio, for free, and as a diyaudio member to copy the design in an effort to take business away from our own diyaudio is at the very minimum unethical.
There's often a difference between the law and plain human decency.
Design your own stuff and make money from that!

I'm afraid jcx is right on what is legally actionable, the best choice is to point out and shun those that are not decent. BTW DF96 disagrees with us, I posted a few weeks ago the exact paragraph from the US code, but I can't find the same for anyone in the EU. Finding things paraphrased to remove the legalese leads to misunderstandings.
DF96 and jn seem to be taking a break.

yes that is my point there is no "moral obligation" to "respect" a claimed circuit beyond active patent coverage
the claim of some sort of control is invalid in its basic conception - circuits, ideas becoming "prior art", "common heritage", free for any to use, modify is how tech advances
same as with pointy sticks, fire, pottery, bronze...
if Jan wants to carp about a circuit being attributed to him that seems strange - since that's really all anyone can expect if the circuit was published, not patented, or patents have expired
if he thinks some have crossed the line into using his name in advertising that is actionable
and exact copies of his art - article, pcb layout are protectable under copyright

Are the last few posts referring to Sikahr PCB's?
From what I read, he created/designed some PCB's from some known published circuits and open up/shares his work in the PCB shop so that people can purchase the boards at their own risk directly from the PCB shop. He neither copied an existing board design nor sold his work for profit.
I don't think he is selling someone else's IP to make money. He is probably just too eager and enthusiastic to share his work and sounded like he was selling. One thing that he might be wrong was not including credits to the original owner of the circuit. However, due to the minimal testing, perhaps not including the original circuit designer's name is a good thing

Before I posted a thread about a mini version of Walt Jung's diamond buffer, I mailed the draft to him first for his feedback,
and his approval to post and mention his name.
When I did a 78xx-pin-compatible mini PCB of the "Super Regulator" I actually made two examples and sent them to Jan Didden for testing.
No law in the EU or elsewhere makes it my obligation to do so.
It is just decency and respect.
It shows what sort of upbringing you have.
Nothing more, nothing less.

sorry but I don't see any issue of politeness involved - if you wanted to add notes on your personal correspondence with Walt, Jan add their comments to your post/article/project that's fine
but there should be no perception of obligation, either "clearing" with the authors before referring to the article you are citing as a circuit inspiration or to use any disclosed idea
from the moment it was published in an article in a magazine "the owner" of the circuit idea is/was The Public
if no patent application had been filed
in most of Europe publication is an absolute bar to patenting - publication is giving it away - this had been the standard for long before Jan, Walt started working on the article - he has no excuses for his unreasonable expectation that someone should let him in any way control the use of the circuit for the rest of his life
I never asked Otala, Cordell, Cherry, Gilbert, Pease, Williams... for permission to link to their publications, comment on them, use circuit ideas, equations...
and have no intention to start, don't expect anyone to argue that I failed in some duty of politeness

Read my post. I SPECIFICALLY reiterated that I don't claim anything here. I ONLY said that since I provided this design to diyaudio for free, to help defray the cost of a forum we all like a lot, I would hope that this design would not be used by someone else to take sales away from diyaudio for personal gain. That's ALL.

So Richard, how much more do you want?
The data shown (THD and FFT) do include the signal source harmonics also
