The best amplifier i have ever listened too..i am glad to present you the Dx Blame

[Arnaldo P]

I will do my best to produce both language narrative in future videos.

Vou me empenhar em fazer as narrativas nas duas línguas daqui pra frente.

abraços,

Carlos

Carlos, thanks

Obrigado Carlos.

[video=youtube;uqH348YkOOc]http://www.youtube.com/watch?v=uqH348YkOOc[/video]A video about Dx home, my addiction, my stuff, last update to the Dx Blame MKII Supercharged and Dx news

Arnaldo..não tive saco pra fazer em portugues..... também não tem nada que eu não tenha dito uma duzia de vezes via email...Nabuco tá ocupado para atualizar as coisas...conto contigo e com o Gustavo para espalhar as noticias quanto ao Supercharged... os transistores grandes para Q6 e Q7, a resistencia de linha que já é de 2 watts mesmo, os dissipadores para Q6 e Q7 e o ajuste de bias medindo as resistencias de emissor que devem ler perto de 1 milivolt apenas..a remoção do adaptador em L e o uso de 1K como P1..isso é tudo.

Arnaldo, i had no patience to make this video in portuguese.... also there's anything that was not already informed you a dozen times using email messages.... Nabuco (Mitchel) is busy to change things in his site....i wish you and Gustaff will explain other guys from HTforum about these last updates... and they are..big transistors to Q6 and Q7 (MJE15032 - To220 ones)....rail resistances are 2 watts but the board already said that..it is printed in the board silk screen... the heatsinks to Q6 and Q7 and also the new bias adjustment where you will measure voltage drop above power emitter resistances and should adjust till you have 1 milivolt or less voltage drop over these resistances (they can be different..no problem if one is 1 milivolt and other 2 milivolts).....use 1K as P1 trimpot to allow you to adjust.

Dá um trabalho louco fazer video nas duas linguas..gasta uma manha inteira cada um...não tenho paciência não Arnaldo.

To produce videos in two languages represents several hours (6) of hard work..i have no time and patience to do that Arnaldo.

regards,

Carlos

Carlos, you are a crazy man hehehe, but you are my idol. i've a lot of stuff and eletronic devices in my apartment

my wife don't like it.

i'd like to have much more time to assembly some amplifiers and another eletronics things.

hugs.

 

[destroyer x]

Wife is always this way..they hate our stuff...our mess...our big speakers destroying the home decoration..this is normal..also they want our attention to them .... exclusive to them..... they hate that you love another woman (electronic).... they will never tollerate the stuff.....you should figth by your own space to leave.... i suggest you agreement.... say.... Sunday nigth is mine... after 5 hours i will go to electronics and i do not want to be bothered.

regards,

Carlos

[gchim]

Good idea Carlos.
i've tryed have some agreements, but no sucess.
i'll never give up.

 

[destroyer x]

No problems..let it be.

Here you have second part, in portuguese, of help to my brazilian friends.

Sem problemas..deixa estar.... aqui tem a segunda parte de cuidados com o Dx Blame MKII Supercharged:

Carlos acabei de registrar aqui no smps para dar uma força ok

 

[destroyer x]

Very good your registration Beto

Thank you.

Harmonics

CARLOS



You told about harmonics in other amplifiers, due mismatched transistors


How your amplifier OVERCOME this major problem?

Or is the design makes it solved?

 

[destroyer x]

Not solved....i would like people to use mismatched (this happens normally as PNP has always more gain...hard to be matched...possible but hard)...these harmonics are really lovely...i would like people to have it...this sonic colouration is nice and usually much appreciated.

I have matched one unit to compare....perfectly matched, i found sonics stérile....lifeless when compared to another channel made from junk parts....at the end...the music beauty comes from these harmonics....harmony and harmonica is what people uysually loves...some production of tube like harmonics are very welcome....well...this is deeply personnal, very subjective stuff....but seems people is enjoying a lot... i am having no complains.... exactly the opposite..people feel the amplifier better than others and use to say they are deeply happy.

The distortion informed (0.003% THD) is from simulator, and serves to the ones evaluate audio by numbers....i don't....i do believe and i am sure about, that real world is different than simulator products, as simulators have matched references and real life things faces enormous mismatches in values of components (tollerances).... the real thing is not simulator results...real thing is audio playing and humans evaluating...when we have the "good harmonics"...we feel good and we appreciate the amplifier.... gladly people does not listen from the simulator..or they may dislike the sonics.

In the simulator usually transistors do not even burns...you can put 2N2222 draining 20 amperes...funny thing.... only fuses use to burn in simulators...so.... they're a nice tool...but just a tool.

Audio, as you know and may agreed, is made for humans, and not for instruments... we could never see instruments going shopping for audio equipment....but human goes shopping..these are the ones we have to satisfy..not instruments.....we have to make audio for them (humans) to make them happy and satisfied....not instruments.

In my signature line you will find the link to an audio message uploaded to youtube as a video....i am there talking about me..about my audio life...i am presenting myself to the ones does not know me.

hello friends ... DX I'm with you. Sorry if wrong in English. Good thing there's uncle google. Charles and other colleagues will be here from today, and let it go

 

[destroyer x]

Yep...let it go.... we gonna have fun here.... be sure about that...soon we gonna have MKIII and then we gonna have MAKO.

regards,

Carlos

Nice to have you here Eduardo pehlse.

Legal ter você aqui Eduardo pehlse.

[video=youtube;NORmStFg5g4]http://www.youtube.com/watch?v=NORmStFg5g4[/video]Yep... Pehlse is very nice...good that we have him here with us:

Multilanguage message...everybody can understand that.

regards,

Carlos

 

[destroyer x]

Pehlse, from Brasil, have built the Dx Blame ST using brazilian green boards made inside a brazilian forum..in a group buy..these boards are not available anymore.

Carlos

 

[efragnani]

Ok, i'm here too! My english is too bad, but let's go! FULL POWER AHEAD.
Regards.
Éverton.

 

[destroyer x]

I am glad to see you here with us.

Bom ter você aqui conosco.

Carlos
