The plot thickens.........

Or, in reality, sickens.

Ok, this is old stuff, but someone over at The Pub brought this up.

http://www.moxtone.com/Uskok%20Preamplifier.htm#schema

This comic genius, of sorts. On one hand, he claims that DIYers steal the ideas of other folk. Because that is what they do. But, he then goes on to say "You better not use this for commercial purposes!"

Considering it is (in theory) derived from the fabled Blowtorch preamp discussions (on some other forum), then one could say it is a reasonable facsimile of the actual Blowtorch schematic.

Would that mean The Devil can't use his own schematic?

Funny stuff.

The real funny stuff is the prologue. He states what he has done, but denies it. And blames the accuser.

Is this guy really an American lawyer? Sure sounds like it!!!!

The bit where he takes swipes at a certain very well-known IC op amp designer............I have no idea what that is all about. But, it sure is funny. Even if only partially (if at all) true.

Anyway, those of you have been sucked in, looking for Blowtorch Preamp Schematics...............we got another one! Thank you, oh great almighty evil Google Empire.

(Translation: if you believe every damn thing you see or read, on the 'Net, I have a certain bridge I would like you to consider purchasing.)

Enjoy.......... suckas.

"Do as I say, not as I do" must be more of a world-wide concept than I thought.

Love those big toroid power transformers...   :-X

I have no idea who this guy is..................

But he sure has a way to get under the skin, of the usual crowd, at The Pub.

Although I am partial to The Rutles version:

"I know you know what you are but you should know by now that you're not me."

Or, to put it another way..................

I am not who you think I am. Yet, some of you think you know.

Good............keep up the good work.............think what you want, because you are almost always wrong.

(Even when you copy my work.)

Back to our regular programming.

Is anyone still reading War and Peace, over at The Pub?

If so, can anyone 'splain to me wtf "micro DC" is? Sorry, my Canuck to Redneck transmogifier is broken. I can not de-gobbledoogook it.

Ok, to be honest............about the only thing he says that I can remotely understand is his new signature. Anything would be an improvement over his old one. Whether is true or not...................not my problem!

I have enough, as it is. Like why I can't eat pizza any longer........

(And some of you folks still wonder why I am in a grouchy mode.)

Real "micro"

Seagreen, you are good with explanations. Please explain to me, could power supply be made even more complicated?

Put two in parallel to reduce the impedance by a factor of two?

The goofy thing is that many of the challenges of power supplies aren't even addressed!

Yeah, three in a row then three in parallel, to maintain balanced operation in all 4 quadrants  ;)

To me, funniest thing is that he is using feed-forward shunt as suggested by Maxim in the EDN article, but there are more appropriate solutions in the very same article.

As long as he's happy...

Personally, it's way too complicated for me.  I can imagine how the electrons feel.

Wow...intimidating. I'm too lazy to even figure out how it works.
La grande complicazione....and at the end, it tells only the time, isn't it?



Maybe in the case of this regulator, it tells it even worse than a CLCRC, which is less affected by PSRR degradation up into the MHz than an OpAmp, and followed by a more simple regulator.
And why not use schottkys instead of MBR rectifier diodes, currents and voltages are low anyway?

Yeah, but caps, resistors, and especially inductors are so low tech.  Only a couple terminals each, too.
