The preparation, the construction project, the study made, this is lovely

This young man has expertise..he is very good...more than good.

You gonna see his work quality.

Prepare yourself to see a Master of amplifier construction working.

regards,

Carlos

Adjust the stand by current is an easy task to be made in the Dx Blame ST

easy adjustment using multiturn trimpot, also normal ones works fine..you can adjust in 10 milivolt steps without any trouble or overflow or unstabilities..once adjusted..if keept cool, the current will remain stable.

See the lovely picture made by Dx Germany.

regards,

Carlos

Hi everyone, just finished reading all posts in this thread. Whew!
I apologise for no picture as I have no digital camera or pictures, scanner etc. to supply as you request for this forum. Hey, you could call me Ian1950 if it helps.
I would like to thank you DX for tolerating the Teknofiles, exaktocrats and Ireadthatbooktoos out here. I'm going to talk to Greg, who's about 500km from me and see about some BLAME boards so I won't be talking through my hat either.
Someone (not DX corporation member) recently posted a string of PC oscilloscope images to illustrate their own point and I gotta ask, realizing that good oscilloscopes, even USB ones are expensive, that there is little point posting wonderful measurements of DC to 20kHz brickwall bandwidth on devices that are required to perform reliably well beyond that. How many harmonics of a 10kHz sinewave does he expect to see in a THD trace? If you like sound card scopes, fine for you. I can't believe that anyone would try to make statements about amplifiers with most of the meaningful data missing. Even $5 "T" amps can look good here.
Sure, I'm no genius either but this has been a great forum, a real cliffhanger - just like a movie so I'll stick with the enthusiasm, perseverance and good will of "uncle Carl" keeping the show afloat. Great Stuff! and to all you "alpha testers' out there, thanks guys!
Best regards, have a nice single malt for me.
 
So: there is another one beginning to assemble the BlameES (Version 1.4):

Lucasz from Poland

Welcome in the club, Lucasz!
Enjoy its amazing sound!

I hope you will publish some pictures showing your progress!
But please: use small ones, not as big as my ones.
The moderators are unhappy with big images!

Best regards - Rudi_Ratlos

An externally hosted image should be here but it was not working when we last tested it.

Thanks for your kind welcome DX. Whoops. See what I have done already! I am a bad influence so I'll just have a think about how to go about building this little Blame ST gem. Maybe a half-width rack case like a Naim or a square box of extruded al. channel sides, just screwed plates over the top and underneath. No sinks needed for <60W! What do you think guys, since some good and big ideas have been used up already. The Corporation's German Division has been really impressive there.
I'd like to try the other way so I'm open to smaller, economical ideas.
regards
 
Thank you Ragnwald, for your consideration. I guess that I am too lazy to say fully what I mean. I should have said "A conventional type of heatsink is not warranted". That is to say that I could safely use a bridge or just bolt O/P transistors to the case which may be 4-5mm thick if a standard shallow channel extrusion was used for the sides. Yeah, a picture is better than 1000 words- sorry!

Anyway, just to clarify that this approach is quite 'sound' (Haha) for domestic Hi Fi, google Naim Audio's UK website and navigate to the discontinued model gallery. It has pics of the inside and out of the amps that put them on the Hi-Fi map. Now, take a close look inside NAP 140 - this is the one all those Ebay kits are said to clone. Do you see the reality here guys? Yes, it does make you think about the "boots and braces" approach we assume will be necessary.

Sure, if we give the DX BLAME uncle Carlos' torture tests of full power into 3.5 ohm loads all day in a 30-40 degree ambient temp. they gotta be big. Yep, time for calculations!

You know, Conrad (Melbourne) is about 1,400km away from me (midway between Sydney and Brisbane) and I bet he's busy thrashing the ULD amp as far it can go with its beautiful thermaltraks. Oh, wow!
Anyway its 28 degrees here, calm, not a cloud all day, the surf's gentle. Button up in your furs and plough through the snow guys. I know you must suffer. How's the ash fallout today?

best regards.
 
Please Rudi, let me know if Volker is using.... still using, the first Blame ES

schematic?.... i am using it here..it is playing rigth now..... sounds very good... seems to me even better than the upgraded units (ST, version 1.4, 1.45 and 1.5)

What is the one you like the most?... i would like your review.... as you know what you are doing and saying...no problems if have criticisms.... you have build, so you have the real experience and has the rigth to talk what you have perceived..this is important to me, and to future builders.

Please, describe your system...some small pictures may be interesting (small to be many!).. your speakers..the crossover it has inside, 6dB?...12dB?...... acoustic suspension?... what drivers?... what nominal impedance?... the audio cable..type, length.... the listening room, rectangular?...have carpet?.. have wood..is it reflective or more absortive?... the music..... if are these ones you send i can make recording to show people the style.... all this is your "system"...and this matters.

Have you found any week points...mufled audio bands.... noises, harshing or anything else?

And temperature?.... have noises?...have power on thump?...have power off thump?

I have anything to criticise...but you know... of course i am biased.... i am the father of this amplifier... our sons are always perfect!... even knowing the are not... we use to think (twist the reality) they are.

ahahahahah🙂

regards,

Carlos

Negative....i love some social, some off topic produces a pause

human relationship is interesting too.... i like that...to me, humanity is always on topic.

Be confortable to say whatever you want...i really like this way...when i can i do this way..i just do not go repeating for several consecutive posts (4 or 5) not to break rules.

How can i respect your inteligence, you sensitivity, your skills... without knowing the man you are.

Remove if you want it...but not because of me..i love these things.... human conversation... also when people start to chat one to the other too.

In my own Orkut forum, everybody is building their own designs...only electronics there..but today and yesterday we are discussing Coca Cola... we are trying to understand the formula...electronics and chat.

regards,

Carlos

Ok, i have build version ES 1.4c with PCB layout by Rudi, this is playing stable and very nice day by day. Now, just at this time, i´m building a second pair of pcbs with same version but original layout.I will not change anything except the outputcoil, this will be installed orthogonal this time ;-)

Thank you Volker..... if you like it, then keep your version

the main modification is the first VAS emitter resistance, increased from 100 to 220 ohms..and the insertion of a resistance in the second VAS emitter..... as i have informed, i had a strange supply that created me problems... all these versions are working stable as i have all them at my home assembled and playing...including the last version too.

I do like the first one.... the one you have is the one i like the most.

As you have assembled, and long time listening, maybe your evaluation about the amplifier have changed as times passes by...i will be happy to know what you think about this amplifier today, as you had chance to listen it carefully for a long time and to detect qualities and defects in the sonics..also you had chance to compare, to readjust bias...so....you have the kind of know how very much interests me.... the ones that really can make a review, and will be more precise.

You know..first moments have a lot of emotion...second day we use to find something not perfect....and this is what interests me to know.

Thank you by the pictures, Rudi is inside a train to Hamburg and i will be waiting his return as i would like to have a review from Rudi too.

Make that in separate please, not to have influences between friends..one influencing the other ..... and try the amplifier without pré amplifier, as this can helps, but can also reduce the audio quality.

regards,

Carlos
 
Ok, i want to build a bridge between the violin and this dx blame es....not easy but possible 🙂)
Here is a kind of musik on my computer, stored as a flac file, called "The Spirit of Gambo", classical musik with Chello.....ok, not a violin, but very near and familar....
so, lissening to this musik with this amp from Carlos, mhmm, that´s very good, real and live, you can feel this spirit, right into the last little hair!
And that is what Carlos has done, a very sensible amp, which can reproduce things like this.
then some people came and told about some sets of measurements, Carlos was lost in a bad transformer, has done something nobody will do with his amp...and ups.....some mystike changes are blown away the spirit of this amp.....
hehe, that´s called demokratie 🙂))
I do´nt like Carlos very well, but his amp 🙂
Carlos has this kind of spirit you do not can measure, and he can be very unfrendly, and he had done a greate work, don´t forget this!!!
 
Thank you Volker...you will be appreciating me near future

To appreciate people, sometimes is a matter to give them a chance to know them better...sometimes we deceive...but many times we can change our point of view.... yeah...there are some we cannot stand for... sadly this exists.

You know, i had figth with Mr. Professor...now a days he is a friend...also Sakis...and we are alike brothers now a days.

I like you.... was angry because the "roller coaster" words..but i am not angry anymore..when i dislike things i use to open my big mouth immediatelly....but soon i use to put these small things in the place they deserve to be.... trash can...life is short to be loosing time with these small crashes.

I am glad you are alike me...you say things directly in people's face.... this is my style dear Volker...we have much more than you can imagine.

Thank you by your review.
