Ian is talking Australian, similar to english, but still difficult for non english readers.

Any designer might prevent this by testing his products in a temperature chamber, under whole range of output power, continuously loaded.
Yes AndrewT, this one, dear Ian Finch, is specially complicated to me
It is very difficult for me, my English came from the school basically .. the early years of school had English as binding, also had French as compulsory and German as an elective course. Portuguese, naturally, was mandatory .... my native language ...the english i have learned was something very basic...introductory of conversation. the way i have explained with the sequence of phrases i have posted.
As an adult, my sister married an Englishman who came here to work for Xerox, he was a little bit boring , neurotic and socially intolerant...but audiophile, addicted to Bang and Olufsen, he liked me and because my sister was almost crazy for him, then i was elected, by the whole brazilian family, to be the one to pay attention to him.. I learned a little with him, while he leaned almost anything about Portuguese with me...he was very bad to learn languages, despite a very intelligent man, his pronunciation was terrible.... this man stole my nephew when his marriage was going to have an end...the boy now a days lives in London, and do not speak a single word of portuguese anymore... while here, he was in school and had perfect control of the portuguese language.
I usually visit google translator, and i use to do it several times a day .. there are words i cannot understand .. if you use idiomatic expressions...or some kind of local way to talk..then i lost myself...i never know if the one is praising me or cursing me ... if the one has agreement or the opposite...or even if he is asking me to go to hell...or comparing me with the divine.
Because of this forum i have found my nephew.

Carlos

DX, I honestly don`t see any significant difference in design of your amplifier versions. What`s the catch in starting a new thread every two weeks with the same design?
I am searching for solutions. researching, trying variations around the same theme
checking if CCS can be helpfull or not, trying things Bodgan.
The reason why?... to be happy, to be doing things, to have hope i will find more answers to my questions about audio, to be learning, to be exercising.
They are almost the same... but they have some of the possible modifications too..exploring things.
I use to post one each week because i am productive, i have time Bogdan..all day long to do that, and i use not to post all my amplifiers, as i use to make one or more each day..from time to time i use to post something....
Troyan and Fokker are almost the same.... if you have readed the thread, you would have the answer...one is development from the other... Troyan is the Fokker having the V/I limiters i do not like but my friend Sakis likes..so..was made because of him and others that loves such things.
All these things are tested, build and listened..so, i am offering tested things, real things.
What is the point you feel bothered or curious about that?... and why to be reading the thread you feel so strange and needing some creativity maybe, as you perceived the amplifiers almost the same....sorry..i am not too much creative..i keep trying hard.
All amplifier started with the Dx amplifier topologie..then i was introducing sub circuits and variations... well... this is the topologie i like..so i am limited.... as almost everything should have the bootstrap.
I am productive, an active person, i am always doing things..do this bothers you?.
Fokker and Troyan are just an exercise... to make a powerfull unit... to test and listen...it is serving to show and prove folks, that overcomplication, usually is counterproductive... result is not so good as the Dx Blame ST..... this is good...i am helping them to think about, to know that sophistications does not represent audio quality.... giving to them tips and tricks..they can assemble and perceive that by themselves..anything hidden here, everything tested, assembled, honest things...real things in the place of simulator things..virtual things we cannot listen nor evaluate sonics..... Fokker was not released.... it will be released, maybe, in July sevententh because reasons exposed earlier in the thread.
In six years in this forum i have made, and released (not experiences non released alike Fokker and troyan) some amplifiers...the Dx Amplifier, HRII, Precision 1, DHR Turbo, Trust and Dx Blame ES.
Please Bodgan, observe 6 years have more than 280 weeks...i have not made 280 amplifiers, i have made 6.... average is one per year.
What is the point to exagerate this way?

Carlos

Dx Corporation Annoucement, a chairman message to friends.
The guaranteed of reliability of the amplifier Dx Blame ES
was removed / canceled/voided ..... the amplifier was
renamed, the circuit was changed, also the ending name changed to
ST which means stable, all was done in the name of safety,
reliability and to provide forum folks, and independent builders,
a good amplifier you can trust.
Almost all the mess i have faced, was caused by a toroidal transformer
faulty, which I suspect has a problem with
it’s core..maybe, cracked, broken and glued... was not dismounted
to check this..but seems i had some magnetic trouble.
The former Dx Blame ES sounded wonderful, the best
sound I heard in my entire life, and continues to sound lovely at
my home and in more than 20 different homes ... half of that in Brazil and
others outside Brazil.... however shows intermitent signs of a
small oscillation in the positive half cycle, and superimposed to the waveform
modulating the flat Dc portion (horizontal) of the square wave
quite large, 500 millivolts peak to peak .... and the
worse, is intermittent .... bass performance was timid, was shy also.
The new brand sufix, termination, the ST... that means stable, was created to show you these amplifiers are different, not only in the schematic but also in the performance while reproducing audio....differences you can easily listen and also can be measured in the slew rate and in the waveshape displayed at the scope
The current Dx Blame ST has different scheme, different performance
can reproduce huge thunder bass and also is perfect for measurement, i could have 0.00017% while tweaking and tuning capacitors, resistances and trying other transistors...while the former Dx Blame ES has 0.002% THD... both plays music with excelent quality, despite i like the former Dx Blame ES the most, i know it is not the best to offer to our forum, because technically it has some flaws.
Dx Blame ES uses a 18pF capacitor in the NFB line, when Dx Blame ST does not use this capacitor (Kroto modification).
Dx Blame ES has a capacitor of 470pF from second VAS collector to the ground .... Dx Blame ST does not have this capacitor
The Dx Blame ES has a resistance of 100 ohms in the first VAS stage, it goes from the first VAS emitter to the negative line, when the Dx Blame ST uses 220 ohms in the same position.
The Dx Blame ES uses 82pf as miller, ... the Dx Blame ST uses 100pF.
The Dx Blame ES has no resistance in the second VAS emitter, when the Dx Blame ST uses a resistance of 10 ohms in series with it’s emitter to the negative line.
The Dx Blame ST has lifted ground in the input, since the Dx Blame ST does not use lifted ground.
Because of numerous failures occurred, and unpleasant setbacks, also awfull surprises (the Transfomer), I decided to change the brand name sufix, the brand name termination , to relieve an amplifier having another brand reference, as in fact, they sound different and have significant changes in the circuit, which are not cosmetics, they have influence in sonic performance and in measurements.
Soon I will open a new thread ....” Dx Blame ST – builder’s thread” in the
Anatech style.... to separate an introductory thread from the thread used for
builders to post their adventure and pictures....new layout will arrive soon, having only the the ST in the title to avoid confusion.
I cannot guarantee the Dx Blame ES anymore...that one, make it under your own risk...sounds lovely...i do love it, i do have it and i do listen to it..but it is not completelly safe....nor entirelly reliable... less technically perfect than the Dx Blame ST that i am offering you...but also saying..if you want to take some risk...then try the former amplifier that has the most beautifull sonics i have ever listened too..maybe the flaws, ringing and so on are what are doing that “magic” in the sonics.
There are much more secrets in our works than our ignorance can even imagine.

Carlos

You do not need to read Bogdan..... maybe to search for other threads with
smaller posts may turn you more happy.
Thread has thousands of hits..seems people like..they return to read several times... you may be different and should search for your "own beach".... another place that may have your style.
This is the last answer to you... your postings are not interesting to be answered... when we have anything intelligent, or kind ot say, better not to say.
Be happy, i hope you heal from your troubles and become positive and happy back again.

Carlos

There's a very nice day out there.... you should visit Brazil folks
First Rio de Janeiro and them the Brazil Northeast.
Bring your main documents...you should never return to your country, there are millions that have not returned.... they're living here:

Again and again you are insulting anyone who has a different view from yours, anyone who does not show enough adoration to your designs and writing style. I do not understand why you are allowed to behave this way, many other members were not treated with such tollerance of mods.
Communication
Hi, everyone
I apologise Carlos, and to others for the problem. I felt a problem in your words, my friend. I guess long sentences don't help either, in any language. We have now reduced Cdom and increased global feedback! Ahahahahahah!😀
Pavel, of course you are right. However, the situation of a designer/manufacturer is unique. It is something very special when you have high demand and prices for a simple product, too. There was a time when the company, it seemed, could put bricks in a case and get a fabulous price. There was enthusiastic press, fans an crazies etc. who knew the sound was the best. -all history.
Andrew is wise to avoid making such comments. There are probably some old, crazy fans in his area with those bricks!

p.s I don't care -still building ES !

I am sure Carlos does not need a bodyguard 😉 .
But as I am reading Bogdan's reply:
Long post again...
Cheers Bogdan!
I would like and ask him: "What is the message behind your post?"
(A typcial manager's phrase - I know - but it is a legitimate question.)
Is it criticism? - Too long a post - too little essence?
Is it envy? - If I had the time you have I would write love-letters as well.
Is it lack of knowledge? - I understand only the half of what you wrote.
I can only guess when reading Bogdan's post.
So what?
Best regards - Rudi_Ratlos

There can be comment and there can be rudeness. I don't think people get silenced because they disagree. Ragnwald has indicated a much better target to accuse of these things.
Yes.

The forum is free....people can stand for some threads or not
strange is people that dislike the style and goes visiting the thread very often..what they want?.... they dislike, do not feel good, do not appreciate the style, long sentences, my thougths and opinions, my amplifier and so on..what they want?
For me is clear and obvious what these ones wants.
Well...let's go ahead... i have a mission... an amplifier to take care.... i am here very often, watching if there's someone i am have a chance to help... sniffing chances to do something good...others seems do the opposite..their problem.
I would like moderators to protect me Pavel...i do think i deserve that..to point people that is clearly trying to bother, to unstabilize, to give me a hard time to be away from the thread...and if they really could do that.... a couple of guys would not bother me anymore... they do not protect... they tollerate when the guy is usefull to the forum...when the guy do something good..when the guy has made something good along the years... they also have some restrictions to my way to be as i am not patience with human weekness alike envy and these awfull things happens from time to time.
They clean the mess and the dirty... if we figth and became in peaces they will come to clean the house....ahahahahahah!
I used not to read you Pavel.... when i feel curious i take a look and i always perceive the old behavior you had with several guys in this forum... they observe me Pavel...and observe you too... wanna know what will happens at the end?..we both gonna be banished, or we gonna feel so bad in this forum that we gonna abandon by ourselves... forum will continues... despite our differences.
Why don't you take care of your business and let me doing mine?... will be better for both of us..also to forum folks..you are a skilled scientist...i am a skilled builder... we both are very usefull..if i died or disappear or be banished... forum will loose..folks will search for someone to teach them to build their first amplifier and will not find for uncle Charlie... scientists that wants to discuss waveform details and methods of measurements will feel bad without you.

Carlos

Do you wanna know?... really wanna know?...this is the best wide world amplifier
ever made...by Doctor Self, by Doctor Hugh Dean and others..... i have made a very good job joining sub circuits.
Better to build folks...to have enjoyment...this is positive..this is to search for happyness.
The rest is rest...just that... some stones in our road only.

Finally, dear Todd Johnson could find some spare time to help me
and the Dx Blame ST schematics and all files are ready with the ST name printed on it.
So, in Greg site you gonna have the new files.
I will recall the " Dx Blame ST - builder's thread "..there i will help the ones will build and are building and will not talk anything out the topic.... the guy is building will have attention...not building will not have the same level of attention there.

I have ordered parts from digikey came to 52 pounds.
the bc556 signal trans was not on the minium order list so the assistance ordered me this one MPSA56GOS-ND. i tried comparing but the only thing i see the difference is the mhz. is this trans crap which one is better?
the pinout is other way around on the MPSA56GOS-ND
