I love to make videos...and there are a lot of them if you type "destroyersoueu" in the Youtube search bar...more than 500 videos, and several in english and about the Dx Blame amplifier adjustment.....i have new model..the Supercharged using blue boards... soon i will talk about if there's someone interested, of course.

Here is a video... a slide movie about things i have done these last two monthes:

http://www.youtube.com/watch?v=4by8NCxxKoM

Adjust volume up... crank it all the way up...you have bass in there.... increase your bass and treble high end..use the loudness contour in your computer equalizer...and enjoy.

Have they kicked you out? learn from this, you are only a
number for the attainment and realization of their interest
and this is the rule of the game in that place you use to be
Will you stay this time with us, so now you are back again.
Have then punished you once more?
Will you continue to work for them when they show you all that respect?
looks alike someone abandoned that needs some house to stay or you're
just wainting for the rain to pass

You seem to be a little bit acid dear Justicer, but you are not entirelly wrong about something.
well....my stay will depend mainly in the interest demonstrated by my amplifier...i am here to help.... having people to help i will for sure stay.

Amplifiers secrets

destroyer


Please clarify one thing to me, I see that your amplifier is so simple in design, with some parts, and not complex like others all over the world.

And your amplifier is built by hundreds also, how you can determine its the best sounding amplifiers.

I am really now intrested into making one and compare. But also I need good speakers. and Good music source.


Please let me know what is the sercet in design of that amplifier
, if you dont mind:UP:

59 years building more than 6000 amplifiers is what gave me skills to decide the one is better to my ears..and this one is the best and final design.

It was inspired in Doctor Self Blameless..and there's an entire philosophy around it...search Blameless and please read it.

Was modified and tuned for sonics by me, bootstrapp instead of CCS to the voltage amplifier stages and a lot of tuning made..resulted better in sonics than Blameless that is a little bit stérile..alike food without salt.

The more parts you have, the more distortions in the sound you have...the wire with gain is the reference...some unreachable circuit that most of us search for... something that can amplify without several pasts messing the whole thing.... each stage you reduce, each complementary circuit you remove, the best sound you will have..the most simple the best it will be...people think that increasing circuitry quantity, showing complexity, will make people think and believe the amplifier is better.... but this is not truth.... bad designer use this resource..as they do not feel safe not doing complicated thing to show themselves as great designer..they think complexity is sign of competence.... in my mind is exactly the opposite..if you need thousand parts to make the same job i can do with one part..then you are thousand times worse than i am....usually complicated designs sucks in sonics....you should try.... a good example is Leach amplifier...my god! i gave a double barreled shot on it when i made it once...i hate that amplifier and all full complementary amplifier that doubles the problem sources, the issue is mainly...these two differential in input. and two voltage amplifiers..a hell to match these guys to have a good result.....the NPN differential and the PNP..the hell thing.

Some guys loves leach amplifier, and do you know why?... defect that turns an effect..when you have different gain in PNP compared to NPN (we all have..PNPs have much more gain because the way they are manufactured) then you have different half waveforms...when this happens you have more second harmonics than third harmonics..and this is perceived as tube alike sonics..and people feel good to have that kind of harmonic distribution.... despite valves (tubes) sounds fine, they measure very badly, and sound is good for a lot of guys...so...sometimes, depending how mismatched and bad constructed a leach amplifier style is... the best sound it can produce..this explains why some loves it..but if you make it good..it will sound bad because the whole mess is to join two halves having different parts (gain).

Even showing you small THD numbers, that seems the amplifer is good alike mine that has 0.003% THD..do not trust..go to listen the hell thing and you will see what i am talking about..all them plays music..and the difference in sonics is huge....and comparing you know that you cannot listen other than the Dx Blame ST amplifier.

There's no secret...only passion to search and research...only energy and will to assemble thousands and to listen and to compare with some unt considered top performer....to compare has an entire knowledge and is a very difficult thing to do...say...the setup to do that, the way you do..how you control variable, the method, the care, the details while constructing the set up...how to perform.... this is what made me able to evaluate TO MY EARS..... gladly, hundreds have confirmed that i am not all that deaf.

I was so focused on that .... and this resulted that i have never took care of myself to earn money with my skills.... so focused in quality and to share my discoveries with the entire community...now a days i do think i am an idiot or half retarded (not even an entire retarded..i am just half of them)... a lot of thieves, smugllers, pirates have stole my amplifier.... several are selling in China, also in Germany, also in Brasil and also in Australia...i never could have a dollar of all that.

You have the masterpiece of an idiot that never had other interests than to produce the best..others wants to fool you to offer you complicated things and to obtain higher price because the amplifier looks dense, overcomplicated and expensive..this increases value, price and fool in power.

You must build and compare...make it simple, in a protobard, or point by point..or etch something at your home...to compare... avoid preamplifiers please as they destroy quality (almost all them..with some exceptions based in OPA high quality chips from Burr & Brown...using preamplifier you will never know if the bad sonics is from preamplifier or the power amplifier..i am sure using the power only you will feel satisfied....and this goes to have advantage..all you remove from your sistem will be better.

Carlos

We already have the Supercharged model...150 watts each channel. THD 0.003%....and can reach 300 watts easy per channel if you accept some distortion ( 1% )...already could measure 460 watts each channel...here you can listen some bass if you have good speakers and amplifier connected to your computer:

Well folks, this amplifier had 150 kits of boards sold in the Brazilian forum and 30 kits sold to an international forum.... we have Rudi Ratlos producing boards together Metal, and one international forum intend to produce boards to distribute....but this will delay a lot...maybe one year more.

Rudi is offering boards in a group buy in that international forum i was talking about, in the Group Buy section.

I have asked Microsim to order production of layout and also boards to this forum too... i hope he will accept what i have asked him.

You have a lot of information in Portuguese and English in this adress:

http://www.dx.kinghost.net/

Also you have all Dx amplifier in these home pages:

http://users.tpg.com.au/users/gerskine/dxamp/

and here you have a text that explains something to you... save this text if you intend to build one of my Dx Blame amplifiers:

.................................................................................................................



There’s a chart with all models and values to the resistances that have identification numbers (R1, C4, Q3 and so on)..... parts that are the same to all models have the value already printed in the board silk screen.... parts that may need to be changed to other value are identified with identification numbers (R1, C3, Q3 and so on)..... because the chart will inform the correct value to each one of the four models served by the same board.

Dx Blame ES - 50/100 watts... 8 and 4 ohms - uses 35 volts DC supplies (symetrical)
Dx Blame ST - 50/100 watts... 8 and 4 ohms - uses 35 volts DC supplies (symetrical)
Dx Blame MKII - 50/100/180 watts... 8/4 and 3 ohms - uses 35 volts DC supplies (symetrical
Dx Blame MKII Supercharged - 100/200 watts 8 and 4 ohms with 0.003% THD...and more with 1 percent - uses 55 volts DC supplies (symetrical)

Input sensitivity is 750 milivolts to drive the power amplifier to full undistorted power

Input impedance will depend the model.... Dx Blame ES, ST and MKII is 10K... the Supercharged is 47K

Audio bandwidth..from 5 hertz to 100 kilohertz, - 3dB normal curve

Power transformer to Dx Blame ES and ST is 25VAC plus 25VAC and 180 watts (180 VA) transformer to each channel... filters are 15000 plus 15000uf to each channel.

Power transformer to the Dx Blame MKII is 25VAC plus 25 VAC and 350 watts (350 VA) to each channel... DC voltage after rectification and filtering will be around 35 volts

Power transformer to Dx Blame MKII, operating with 35 volts is a 40VAC plud 40 VAC and 350 watts (350 VA) power transformer to each channel... DC voltage after rectification and filtering will be around 55 volts DC plus 55 volts DC (positive and negative naturally)

Fuses to the rails, Dx Blame ES and Dx Blame ST is 2.5A to each rail and 5A fuse in series with the speaker terminal (speaker protection or use a protector board having relays and delayed insertion and off set (DC) sensor)

Fuse to rails, Dx Blame MKII is 4A to each rail and 8 amperes to the output.... in series with the speaker as protection if you do not use protector circuit board.

Fuse to rails, Dx Blame MKII Supercharged.... 4 amperes each rail and 8 amperes to the output

Attention.... this amplifier is using ONLY two output pairs..but they MUST be the transistor model suggested because huge.... these amplifiers can produce much more power than specified, but having distortions... to avoid power output transistors damage, i have used limited power to the transformers...so..transformers is what limits the power... do not increase transformer power, or you will have transistor damage... also higher power...but will have troubles....to avoid reduce audio quality, VI limiters where not used..so... transistors are not protected and calculated to work fine with the transformer power suggested..if you install 1000 watts transformer you will have more power and will have also output transistor damaged..

Dx Blame ES and ST does not work with 2 ohms loads
Dx Blame MKII can operate with 3 ohms loads, but cannot operate with 2 ohms loads
Dx Blame MKII Supercharged will operate with 8 and 4 ohms only.

You should use star ground... or central ground.... so, capture the center tap wire from your power transformer (s) and solder, or fix it to your metalic case, your chassis.... this is the point to supply ground, power amplifier ground and speaker ground.

The power amplifiers uses lifted ground, or low noise ground (10 ohms resistance).. and this should not be connected to the star ground.... so, your input plugs must have the ground insulated (not connected electrically) to the metalic chassis.

It is suggested to you two transformers, or two supplies, with two separated rectifiers and bank of filters (electrolitic condensers) to each channel to increase separation and to obtain better sound stage.

A kit was offered in the past, for Brazil only, the green boards, and that kit included Surge protection board... 2 boards as Protector boards, speaker protectors... one board to each channel, having a lot of transistors and a relay.... that protector board senses the off set or DC in the output and switches the speaker off if we have a failure in the amplifier..this way avoiding rail DC to go the the output speaker connectors...also provide a delayed insertion to amplifiers that produces noises during power on (not the Dx Blame case...this amplifier has silent power on)... also the kit had two power supply boards and two power amplifier boards.

Another kit, the Supercharged blue boards kit had only protectors, power amplifier and supply.... and that power supply have not rectifier...it is to use external industrial bridge rectifiers because the huge current this amplifier can suck from the supply...so... the supply used only condensers, resistances and capacitors.

There's a video in the youtube explaining how to adjust this amplifier...video in Portuguese and in English too...there's several videos about other details and video explaining how this amplifier works...also a lot of other videos showing it playing and some sllide movies showing pictures and the sonics of this amplfiier...with audio captured using microphone....just type " destroyersoueu " in the Youtube search bar and you will have all these videos and much more.

The kinghost shows boards in details, schematics, adjustments, charts and all needed information to someone to assemble, to etch their own boards in their own home if they want to do this way..also Greg site.

You should read if you are interested..all informations where posted and written for you...you do not need to ask things..just read and i do think you will not need to ask anything more..as i have worked hard to keep all informations opened to whole world.

regards,

Carlos
