Come along, John. You *must* have grown a thick enough skin by now! In
the unlikely event you haven't, just use your KF and move on.

I know a few very good people who won't post here, because the trash
level is so high.

They're not going to visit many newsgroups then. Teach them how to plonk.
Works wonders.

Using four-letter words isn't the only way of being unpleasant. John Larkin's "design something" line is another way of being unpleasant, since it conveys the impression that John Larkin thinks that the target never designs anything.

Not that John Larkin seems to know much about design - as opposed to persistent tinkering. That's being unpleasant without using four letter words ...

I don't understand your logic. You want a moderator to get rid of people
like Allison, but a moderator may not agree with your choice. So I
suggest you simply plonk him. You reply:

"Agent can plonk, but it's easy to just ignore people, and to ignore
entire threads where the usual gang is spinning the usual ritual
insults."

So why do you want a moderator? Just plonk them and stop wasting your
time.

The garbage level here keeps some good people away. A moderator could
just enforce civility and keep the orientation on electronic design.

Plonk works for them also. If they visit any newsgroup, they will already be
familiar with jerks.

Well please don't be one of them.

Cursitor Doom is sufficiently out of touch to think that John Larkin might be a "very good person". John Larkin clearly thinks that he is a very good designer, whose business produces insanely good designs, but Donald Trump thinks that Donald Trump is a "stable genius".

Egomaniacs do tend to have an inflated idea of their capabilities.

It's a really dumb thing to do, made even worse if they announce it.

Much like someone announcing their smelly farts.

FYI:

I have never "plonked" anyone - cos I would much rather know what everyone posting on a NG is saying.

Although the schem on that dodgy site is not mine, it nevertheless would have quite low noise. There are simply NO resistors in the input signal path to cause any excess.

Gain will be in the hundreds and THD low due to the linear operation of the compound feedback pairs.

As drawn, it has no gain adjustment nor "balanced" - as is the norm for low Z mic pres.

To be fair to Alison, he has never claimed to be a designer. He mostly
repairs audio equipment and therefore thinks more like a tech than a
designer. The two have different mindsets and neither can really see with
sufficient clarity how the other thinks.

Yes, no high-value resistor in the signal path, but a very poor
choice of "low-noise" input transistors. The jellybean 2n3906,
operated at 1mA, has an e_n of about 1nV/rt-Hz, see Table 8.1a,
which is about 5x higher than the best parts. The 2n3906 also
has low beta, further contributing noise and poor performance.
It's hard to imagine an experience audio engineer choosing such
a part, when there are so many better candidates. Furthermore,
the circuit configuration is awkward, with no predictable gain-
determining elements. Adding a 10-ohm resistor in each emitter
path would lower distortion, and set the gain to about 200,
without significantly increasing noise. But then, Phil has
dictated that I know nothing about audio, so perhaps we had
better just forget the whole thing, and I'll confine myself
to designing precision laboratory amplifiers.

To be fair to Alison,

** Please, Allison has two Ls - not the girls name.

he has never claimed to be a designer. He mostly
repairs audio equipment and therefore thinks more like a tech than a
designer.

** I do repair work to make a living, it's the easiest way I know.

Professional audio is a speciality, removed from consumer equipment - though I do see some from regular customers from time to time.

Firstly I run my own business, if you have only worked for others and collected a salary you have * NO * idea what a responsibility that is. Makes me liable for everything that happens - many aspects of which I cannot control.

The two have different mindsets and neither can really see with
sufficient clarity how the other thinks.

** I am not your usual tech, I have never come across another one who studied honours level Engineering as a famous University like I did.

A keen hobbyist from before my teens, I like to understand how any item that arrives on my bench works - and of course why it failed.

So, essentially I reverse engineer lots of stuff, all created by "designers" - and built in some shit awful factory by underpaid women.

* Designers are people who have their mistakes mass produced - unlike doctors who bury theirs *

Very often, I am involved in a battle of wits with designers that have given no consideration to repairability OR have included such god awful stuff ups I cannot, in good faith, hand them back to their owners without doing something about them.

So I do a lot of redesign or "mods" if you like.

I like to build my own tests gear, where possible, some of which have been published as projects in Australia's leading electronics magazine. This is not a simple as you might think cos of the severe limitation on such designs.

Published projects must only use readily available components, be buildable by novices, be cheaper to make than comparable commercial items and interesting enough to read about to sell magazines PLUS be commercially viable as kits to firms who sell such.

Managed that juggling act about 5 or 6 times - till the magazine industry finally went bust.

A web site has a few of my designs on it - but I fear identifying it because of the mindless hate I am bound to cop here.

JLs repeated requests that I do so is nothing but a threat.

Wot a despicable pig he is.

John Larkin thinks he designs electronics and thinks that he knows what other people do.

I haven't designed electronics for money for years. I've designed some stuff for my own entertainment, and posted it here, but not when John Larkin has been paying attention.

> My-o-my fussy old hens.

We don't take John Larkin as seriously as he thinks he deserves. He's got a high opinion of his own skills, which helps him make money out of what he can do.

** By the dodgy fool that drew it, not me.

And it ain't really that poor in practice.

The jellybean 2n3906,
operated at 1mA, has an e_n of about 1nV/rt-Hz, see Table 8.1a,
which is about 5x higher than the best parts.

** Might not be very important.

A figure of 1nV/rtHz noise, in the audio band, works out to be 0.12uV rms

( multilying rtHz by 122, the sqrt of 15000 )

Dynamic mics have a source impedance of 200 to 600 ohms, equating to an audio band self noise of about 0.2 to 0.3uV, in a vacuum ...

( En = sqrt 4KTBR )


BTW: Condenser mics are used for most critical recording jobs, they have a residual noise of 1uV or more, due to their internal pre-amps.

So it is fair to say the circuit, as posted has "quite low noise" for mic pre-amp use.

The 2n3906 also
has low beta, further contributing noise and poor performance.
It's hard to imagine an experience audio engineer choosing such
a part, when there are so many better candidates.

** Win, hello, are you there ?

No "experienced audio engineer" had anything to do with the parts choice.

Furthermore,
the circuit configuration is awkward, with no predictable gain-
determining elements.

** It simply ain't my circuit and Win snipped and ignored my comment about the lack of gain control etc.

Typical asshole thing of Win to do.

He still knows bugger all about audio.

It's a big subject.

** Dunno what these mysterious "best parts" are, but a good choice for the same job is the 2N4403. Lower noise, higher beta but still cheap and readily available. See fig 8

https://www.onsemi.com/pub/Collateral/2N4403-D.PDF

Gets down real close to the theoretical noise limit, for a 200 to 600ohm source.

FYI:

Measurement with any kind of *real mic* attached requires "silent chamber" or placing the mic in a vacuum.....

Anyone familiar with Leonard's "chicken in a vacuum" joke on BBT ??

** It's not really, the topic is simply the *discussion* of "electronics design".

You do not have to be a professional designer yourself to possess much useful knowledge about design issues.

** This is JL's big mistake and a major misunderstanding **.

Like one does not have to be a chicken to tell a rotten egg - working as designer does not even make you expert on your own designs.

Rather, the close personal involvement tends to make you blind to errors & shortcomings in your design and the ability to recognise better ideas than yours even exist. Your design is your baby and so you love it.

Good designs are more often the work of teams, with each member able to review and criticise the ideas of the others. Having a damn good look at competing designs never hurts too, in fact it is common sense to do so if only to learn from other's mistakes.

In all the cases of terrible blunders and plain bad design I have seen produced over the years - they turn out to be the work of just one person.

Typically smug egomaniacs, just like JL.
