Blah blah blah. Try actual engineering. Take the verbal diarrhea home. This post is far more than you deserve. I note with interest, that you lied to Morris w/r to what we said. We know your game...and, it is not very pretty.
I have resisted others who call you a troll. Alas, I am losing that battle as others have provided quite salient points.

Sheesh.
Some of the youth today... Totally awesome.
They still have holes in their learnings, that is where we should come in. (You know...us old guys..)
I now find myself in the position of explaining to upper management that they need to hire these guys when they graduate, so have to keep in touch.
Sigh. One can only hope.
Jn
I wish...2 more hours as a lounge lizard.. then off on adventure for 3 weeks
As for filling in the holes, I'm too old and life dealt too many physical blows for me to keep up with those other than my offspring...(son helps run equivalent of internal affairs cybersecurity in San Jose for Apple, daughter engineers interface software for victim notification with national law enforcement depts for Apriss), so I'm doing bucket list stuff rather than trying to improve the world around me... other than occasional audio enlightenment for friends with (formerly) tin ears... ;-)

It is wonderful watching the offspring develop.
But for me, that is only three. And they do their own thing.
I do not want what I know to die with me. We need to teach the yoot of today what they need to continue the work.
Quite honestly, that is why I have so much of an issue with the audio quantum crap as well as the JR "stuff". A diversion from reality, serving only the author.
The young, some a major smart. We are not doomed, even if the path is rocky..

You could add never knew to the list.
How many examples are there where people have forgotten or don't know how things work, preferring to think of them Black Boxes. E.g opamps, DSP, DACs, logic, etc.

I am as skeptical as anyone else here. But at least in a good way, total negativity is counterproductive. Imagine all the things we would have missed out on.
Whatever happened to the important role of intuition in science? It is often there at the beginning of something great.
I am very skeptical about Bybees. I have not tried them and they are also very expensive. But I have an open mind as to whether they work, because I have not yet tried them. That I believe is a reasonable line to take. In fact, the only line to take as far as I am concerned.
No, I am not a salesman, but I get it, this is just another constructed form of pejorative.
Does not work on me for the simple reason, it is not true.
I am an angel compared to some of you guys. I am not a head hunter. 😉
Richard,
The circuit you have shown is a way to implement a current drive amplifier, or more correctly stated, an amplifier of higher output impedance. The actual OP Z will be dependent on the component values of those 3 resistors (in FB path).
.
and? How and why does my simple 1980's mod Reduce THD from the loudspeaker driver?

Classified, give us a break. Most classified, top secret, whatever is politics laced with deception... been there, done that. Not an asset
What Jack has been working on in recent years, including the parts that he recently sent me has nothing to do with his classified past work. Only his purifiers, (so far as I know) were a problem with former government work. His new stuff, he has paid to get researched himself and works on C13 resonance. It works on a similar principle as the Stein products made (I think) in Germany, and they first introduced the concept.
Yes. My expectation is that I will be able to do some very rudimentary checks on the rebuilt assembly, but I do not have the necessary precision gear to measure the distortion characteristics.
So I will keep the shipping materials in good condition to allow shipping to someone else for a more elaborate set of measurements of voltage vs current vs jn drive.
jn
let me know. Would like to help measure for you

Here is proof that F=BLi is always 100% correct.
Sample driver has a DC resistance, Re = 6 Ohm. This is just the DC component of the voice coil. That is important to understand the evidence below - and this is as conclusive as it gets.
Equivalence Test:
Two Graphs Equal:
Sample frequencies (but this can be applied to ANY frequency).
42Hz:
3KHz:
20KHz:
There is no ambiguity in what is presented above. It is easily tested, it conforms to proper maths because of modeling software like SoundEasy, renowned world-wide (do not pirate it) gives us identical results.
Note that the proof is in the prediction, the correlation of the change is SPL, the Sound Pressure Level in dB.
So if anybody wants to convince me otherwise, you have to come up with real evidence.
But I wouldn't try, because it is what it is: The only conclusion is that F=Bli actually works as stated.
[Now I have to get some work done, it is not selling. This requires a soldering iron. Now I am sure we shall see some soldering iron jokes... sigh.]

I doubt if anything that old is classified. When I was hanging around nuc weapons design, under grounds nuc tests etal and had a special and well above Top Secret clearance ("Q")...... when I was debriefed, I was told I could not leave the country for 8 years unless I had permission of government. The 8 years was the CIA estimate of how far ahead of others (Russians) we were at that time (which was also classified info). After 8 years they would have figured out same things we did.What was done 35 years ago is beyond useless. Classified shmassified. Stop running guard for him.
Jn
35 years?! I dont think so.
It is really a shame not everything known can be published or even discussed. Only way to learn some of it is to mentor with a senior level scientist for years. Poor fella who is top 10% of PHD grads gets to be a "Junior" scientist to a senior scientist. Such is the nature of classified research.

works on C13 resonance.
You say this stuff with a straight face just like Giorgio Tsoukalos looks at the camera on the history channel and tells us that early man could not have done what they did without alien intervention.
I don't know which is sadder.

You're showing pure voltage vs pure current drive again, get your story straight. Besides you're back to equating Zload, a complex number, to the modulus of the impedance. You do realize that a reactance can not dissipate power, or do you? This trolling is getting tedious.
Apologies PMA, I can't resist.

I was unhappy that everybody quit the dvc Jn tap thingy, but certainly understand that everybody has a life.
I am hoping my surgery works, and that I can add a tap winding to the vc without it rubbing. Quite honestly, that hands on stuff is what I like the most. I am perfectly happy letting others do that injuneering thingy. Unfortunately, the winding of a 36 to 49 AWG tap wire(available wire size range) will require I lay off the coffee for a day....sucks.
Course, I was kinda hoping some young guys would get interested.
I may yet get some Ph.D. Candidate type interested at the local univ...who knows😕
Oh, forgot to buy some speaker tinsel...can't get the taps out without that.

Thus I am Godfather to amazing young woman. From remote village near the Himalayan mountains of Nepal. Literally Dirt poor. Parents with no education. No money. Girl with no chance with the culture and poverty she was born into. With 160 IQ would have spent her life planting rice etc. Die-ing inside of terminal boredom. Since her father didnt want her (only wanted a boy) I took her and supported her while she lived in Nepal since 5 years old. Now going to university in Sydney. Going to get herself an MS EE degree and also one in management. Loves music and audio, too. We are not doomed. I will leave her to carry on. <3

Joe,
At this point you have been debating everything round and round in circles. Mystery experts for "proof" and in a thread about solid state electronics. The Blowtorch to be exact. You are way, way off topic and really are fitting the description as a troll. I've tried to be nice and suggest you return only once you have at least learned to use the terminology properly. But no, you decided to debate that point and dragged your mystery inner circle into the debate for proof. You are very adept at trying to make an exception the rule.
This does have to stop, and you are unwilling to do so voluntarily.

Yes, and you have to write 1000 times “Current drive good, voltage drive bad, F=BLi”
