Those days i was very young, and those times i had the idea that good construction, .
Beauty of circuits were connected to quality....and quality of design were connected to sound quality.
I was not more than a boy a little bit big....and i bougth this kit and alike a surgeon.... alike an operation.... alike a doctor with plastic gloves i was deep carefull into the construction.... a piece of jewellery the amplifier...good silk screen, good boards, parts well arranged in strips.... fine package.
And i cleaned my hands many times during construction...bending resistors with care...removing oxide.... ahahahaha!.....sanding soldering iron..... using flux to solder...and aligator clips to avoid burn transistor (since them i never used aligator clips again...and i never burned a single transistor because heat.... an enormous Myth!)....and constructed the pretty amplifier.... i found myself ridiculous listening the amplifier... and i decide to put the blame on the aligator clips!...i could not accept so much care with that amplifier...very, very deceptive unit.... specifications was wonderfull for those days.... 0.0X.... x being a very small number...distortion nothing!...ahahahaha!
You may see that the output heatsinks, despite pretty, are very small to big output..... hehe...no big output...clear 7 or 8 volts...not more than that....reason why, the driver sized heatsink was used to output.
Those times, not easy to find more than 40 watts amplifier...the biggest majority of amplifiers in Brasil was underpowered.
This amplifier shown me that appearance is not sonic quality guarantee.... was awfull to perceive that....and also good, since that moment i did not mind anymore with pretty boards...as they do not guarantee any pretty sound.
Old days..... very old days.

Carlos

Oh!...i am feeling very sad....now i know why this guys disappeared from forum..many
Good guys disappeared..... and i miss a lot of them....we may have too much liberty.... freedom.... there are extremes that can produce those things.
And now you search for A, for B, and they are not more with us...John Curl was the one that constantly was together, beeing some reference to all of us.... reason of pride to have him here with us...John also disappeared.... i tried some contact:
Hey John..i want to know this and that from you...your works, amplifiers.
Answer was...search Google...there are a lot!.... clearly one more that do not want to talk too much with us...or... too much busy and i was unlucky to find him in some "bad moment".
And this one about the text published...i will not tell you the name as he want to continue to be happy....he told me that found happyness when decided not to visit our forum...this is very sad, terrible future for us.

Annoying guys are so full of the theories they defend, that they are blinded to other ways of thinking and communicating !
Life is much more peaceful for me now, those last monthes i did not try to explain that there are other ways of thinking about audio problems, to some of those very bad mannered members of 'diyAudio'. I have no wish to ever again read their rants and irrational bickerings - they stand in the way of reproduced music appreciation !
By necessity problem solvers (service engineers) earn their livings by thinking differently to designers and theoreticians. Those who are very experienced through long term hands-on effort and empiricism, develop appreciations that the theory based exponents, simply cannot begin to know about, even though they think they do.
It is because our designers and theoreticians *know* what is right, that our world is now so full of resource consuming junk.
I am afraid that you are wasting your time trying to 'unlearn' such 'educated' folk. Far there are some 'diyAudio' contributors that would rather lose a leg to the metaphorical shark, in their ideal bay, and then think they were more theoretically correct to do so, when compared to those who enjoy reproduced audio, that can be appreciated in so many other ways not bounded by *their* theory.
DiyAudio lacks necessary bandpass filtering, and thus the wanted-signal to noise ratio becomes and *remains* degraded !
Even old JLH thread has been hijacked by those who try devices that are so unsuitable (Mosfets) the circuit can no longer run like JLH design; but don't anyone dare to tell them for they don't know what they are doing and you'll only receive intemperate communications based upon 'their' theoretical knowledge in return !
If there was ever a need for a 'bandpass filter' at diyAudio then it should be on this thread to preserve all the good content therein that has become permanently degraded by those who know not what they do !
.......................................................................................................
Not my text, but i agreed with every word, dot or comma....very sad reality.
Those things are hard to contruct...and easy to destroy...because freedom can be used to destroy.... and worst is that the destruction is made under the name of liberty of expression.

s/he must be talking about the new PLH amp: JLH with mosfet output. Didn't know that Nelson got it so wrong, though.
🙂
Or Williamson got it wrong too?

Carlos, I disagree.
Yes, there are some that do not contribute here any more, I won't deny that. But this is still the most knowledgable and friendly audio site I have found, and we want to keep it that way.
However we do have a house rule of encouraging free debate. There are no reasonable limits as long as the discussion is polite and relevant, but I suspect that this offends some peoples' egos or belief structures. This is not going to change, and so they leave us for a more "Like minded" audience. That's life. I prefer intelligent discussion to mindless self congratulation, subjectivist or objectivist makes no difference.

All in all diyaudio.com is the best and biggest diyaudio forum in the world.
Just wondering, what is this thread all about really?
diyaudio.com is the only forum I know where people are nasty to each other but on the other hand no other forum has this trafic. All other forums are pretty sleepy compared to here. Of 40000 members 2-10 people can't behave themselves so if a forum has 1000 members you won't get a whole person which misbehaves.destroyer X said:

Evaluating by results, observing the number of people that disappeared...i suppose
The selection of people, that will remain, will be fighters.
Rules are rules...and we have to obbey or jump out.
I cannot accept, if you prepare a dinner into your home (our forum as a home), and you invite a lot of friends, and doors opened to community, newcomers entering to have dinner.
And someone start to talk that the food is not good and spell gazes in the meeting without reaction.
This is not discussion...so, discussion encouragement cannot be applied in some sittuations...this is terrorist method to break harmony.... a coward method to use the freedom to spit fire and be hidden behing the curtain of liberty of expression...something fake.... another "We are here to defend Democracy"..things that no one believe.... the intention of some guys are clearly to bother...as you can visit threads and see that those guys agree with nothing.... or even when agree, have some undelicated words to say.... freedom to disturb?
This way, continuing to filter forum people that way, you will remain only with people figthing.
Alike many guys, i am turning tired...and the discussers, that do not cooperate in almost nothing about DIY...just discussing, doing nothing, constructing nothing, destructing everything will dominate the forum.
You can see that quality is going down...you have quantity of guys...contribution reducing..people afraid to contribute and appear some Cro-Magnon to say bad things, without any education...so..... only theoric discussions...and theoric discussions have nothing about DIY.
Or i read wrong, all those times i am here:
Is this forum Discuss it yourself?...or Do it Yourself?
Now more guys...forum clear worst!....contributions less...discussions more and more...fights here... texas there..banishment happening here or there..and observing last three years, the quality decay is clear....confused by quantity increase of persons.
If theorical discussions are good...all guys could find solutions..but they never find nothing!
And if theorical discussions are positive....Where are the EEs?...they runned out...stayed here only the ones that have personal interests, related commerce....the big Enginners are avoiding forum...and those are the ones that can produce conclusions and the happy end of discussions, explaining things and searching for solutions..... i am sure they turn tired too.
Well....Pinkmouse, you are one of the important forum guys..one of the Ship's Command bridge..... you decide the direction to navigate.
God bless you, as this is an enormous responsability.
I will try to enter the forum rules.... to lock myself into the rails... will try to accept negative people alike 99 as something normal that we have to face daily...will try.
Well...the fish was fished (I was), forum move direction..so... will probably be moved...sorry friends...I could not shut my mouth.
Halojoy was rigth!

Carlos,
it is you who tries to evaluate people. Do you have any special rights or abilities to do that?

No...i have only a Psychologist degrée...i have not the rigth
to do those things...only the hability, the capacity.
I am receiving many direct mails supporting my ideas.
Ask yourself, how many guys sent mails to you supporting your ideas and actions.
But this do not give me this rigth....give me courage only.

Are there someone that modified Aksa amplifiers?
Can you please inform here, or directly:
nanabrother@yahoo.com
The thread is about Aksa amplifiers, i will not answer or publish other subjects anymore...hehe
Congratulation Peranders...that was on target!, contributing to thread move..as you are thinking to yourself and writing...ahahha...no intentions of course!....a long time ago... i remembered you as a moderator...oh no!.... i may be wrong... some confusion i am making... sorry... may be some mistake.

I see your point, but it's a fact that in any discussion forum, at least 50% of those that contribute will be "Armchair Generals". There are a huge amount of practical projects going on at any time here, of various levels of difficulty. Yes, some of the complex theory is not as well represented, but by it's nature, that sort of thing is often someone's Intellectual Property, and therefore the industry experts may not be free to discuss their thoughts. But we are always looking at ways to improve the board, and this is something we are aware of.

I asked moderator to punish me, in the place of punish all thread guys
And i am sure that they are analising this with respect.
As my fault is beeing bad to whole group of guys that contributed to the thread.
I will be waiting justice.
I offered my head in place of the thread!

Carlos, no-one is being punished, I am just being tidy!
I moved the thread because it was becoming a more general discussion of audio, and not specifically related to Solid State any more. Thats all!

Carlos, you are crying out: "where are the experts, where are the experts?" If you start discuss anything related to electronics you may start a constructive discussion but at the moment there are just many words of nothing, sorry.
Yes, the problem with some of these threads in this forum is
just that, too many people talking ...and saying nothing...

Hi everybodys 🙂
Hard time for this thread! 😕
I think i can understand Carlos when he say he is tired about some guys saying they don't agree with this or that because many of those guys do not construct . 🙁
I have constructed many amplifiers from others and designed by me and some very well calculated ones sounded very bad.
Some strange circuits (at first) sounded surprisingly good but were criticized by guys only evaluating schematic.
I have built an amplifier published in a magazine some years ago and it sounded very good: almost like a good tube amplifier. Next month in "letters" i have read many bad comments from guys saying they have not built but in view of the schematic they said it was a foolish circuit. Good encouragement for this guy!! 😡
THIS IS VERY TIRING...
It should be fair that those doing the same thing (constructing, testing and listening) have a good discussion: not necessary to agree. 😱
I am shure we can sustain a good discussion without agreeing if this person has constructed and listened. 😀
If we think about Pass amplifiers, they sound good despite having high distortion! Those judging schematics and seeing distortion graph will never build a Pass amplifier... 😉
Many guys have told me MP-3 are as good as CD: if we think about math. they should be right. MP-3 is supposed removing only sound we cannot hear... When we listen (not on PC speakers...)we hear big differences.
Some guys also told me MP-3 is better than CD and they were serious!
MP-3 is an example where math fail in audio. 🙄
Math is essential in audio but cannot explain all aspect of this art/science. 😎
WE HAVE TO TEST!!
I suggest it is time to construct , listen to units and having fun discussing results. 🙂 🙂

Re: Carlos is my Friend. 🙂
I do the math a bit different. 1 -9/10 = 1/10 where 1 is the music & 1/10 is the MP3

You are wrong on that math there dave.. Some Mp3's are not compressed all the same.. some are 64kbps and some are 256 and higher.. then there is losless..
