Dear Mr. Metal,
Mr. Carlos is a very good guy... he really is!
But I tell you for sure: it is easier to understand women's thoughts!
(Mr. Carlos, with all the respect you do deserve!).
I apologize for the rough English...
Regards,
Max.🙂

Hi Metal, I am just a recent "would be" ES builder. We have just this day had a meltdown and Rudi, Volker, Luka, Omar and I have, I believe, decided to continue the ES thread seperately as builders of this model. It does not then conflict with other thread for ST model and does not get any quality seal. I think that's all settled now.
Carlos is still in overall view of this because the design and thread is still his. We have not decided to take his work and trash it, however feasible that is in the forum.
There are now issues for us within this thread to discuss amongst ourselves and, of course with anyone else who has an interest with Blame ES design. It is labelled US now so that there is a clear point of change of control . It is intended to produce universal documentation so that any model can be built from one type of PCB. That is possible now, it just could be tidier or better explained, I think.
The "Blame" is sometimes humour and some irony for us. Please don't take this seriously. We like a laugh sometimes.
regards

Hi Ian,
I have not done any design of any of Carlos's amplifiers or power supplies. I did try to offer some suggestions ONCE, but got my head bitten off like everyone else does. The only thing I did was a PCB design of Carlos's original DX Amp many years ago.
I did redraw some of Carlos's schematics for the website, but soon after that the team expanded and there were others that did the job. The schematics and PCBs should be done by the same person using the same software IMHO so I don't get involved.
regards
Sorry Greg, you will be the one to know. I only repeated a credit Rudi gave for his PSUs. I don't know about the PCB design but as you say, this doesn't have anything to do with Carlos' amplifier designs. Perhaps Rudi will have something better to say on this. Meantime, I hope the injury is healing. Maybe an SC480 next time?
best regards
best regards
Ian, no need to be sorry, I just didn't want credit for Carlos's work. I know Carlos well now so I just keep my head lower now, very low. I have done a few SC480 (T03 type). I was getting them for $12.50 each from DSE, so good value.
regards

It is not so complicated, i just dislike to see one amplifier beeing modified
it is counter producent..... a step back...in the place to have more units, amplifiers goes loosing it's character, and after modifications, some of them loose the sonic signature.
I dislike not only about mine amplifiers.... i turn myself nervous when i see others amplifier beeing tweaked.... in my mind, better to multiply, doing others, changing name, opening new threads, giving forum more options in the place to go modifying amplifiers in the same thread...this turns confused... at least confused.
I just said.... please, do other boards you want, install room for all options, and try not to change the amplifier original design... it was tuned this way.... changing will kill it.... will not be Dx Blame anymore...the same way i tweaked and had two different sonics...and the last one is not the best one.
Change amplifiers, in a thread dedicated to some brand..is not threadjacking...it is amplifierjacking.
ahahahahahah!

With all the respect you do deserve, Mr. DX, I do not bother anymore with what you do think about what I say. I do not use to measure what to say, and I definitely am not going to learn this with you.
I like the way you develop your work, but I think you could be a bit more accessible.
Still hoping to be helpful some day!
Best regards,
Max.
You are welcome Max
Thank you by the preference in my amplifier.
Be happy and enjoy good sonics.
Carlos

Metal stated the following (here http://www.diyaudio.com/forums/soli...m-trying-new-amplifier-142.html#post2180504): "but sure not everyone here understands this person".
What I intended to mean was: it is easier to understand women's thoughts than Carlos' thoughts, or Carlos' way of driving things.
So, I apologize for having been misunderstood. My intention is always to be kind, gentle, and/or funny, if possible.
Sorry for all the trouble.
Max.
Hey, Carlos, nice picture!
But, sorry, i think you are wrong here, this is the DX Blame ES thread....the amp with this kind of spirit you have done, not the comunity-now-is-all-save-version without any magic in sound...!
😀😀
Sorry, please, this was a must be 🙂))

hehehhehe...these ones will be modified to ES man!
ahahahahahahah!
I will take the risk by myself.
Others can take too...my obligation, is to offer the best technically stable amplifier..and that one is the ST...also i have made the best in sonics too (ES)...people can decide by themselves.
One or other, no matter what gonna be their choices, will be good amplifiers, and i will feel good because i did it..so...i feel responsable by their happyness..your happyness and satisfaction too.
Both options will be offered by German Division, and seems you are an important part of this German division....so... everybody gonna be happy..the technocrats and their measurement instruments and the ones appreciates good sound without bother if electrons are spining clockwise or counterclockwise.
All our worries will finish with German boards offering both options..them people build the one they want.
I am very happy.... my work is there..in both amplifiers.
I do not underestimate people's inteligence dear Volker, i am sure they are so clever than you and me..they will take the best decision.

Carlos

You are very welcome building the ES
The ST also have excelent sonics....loose in some details, lifeless sonics... but it is also excelent.
Some small introduced defects, produces effects..guitar pedals, and standard guitar distorters, reverberators and so one. sometimes these effects are interesting for sonics.
Some folks does not want only sonic performance, they want to be sure the amplifier is technically perfect in design, having any kind of failures or bad decisions taken... these ones if face very small oscilations superimposed to the square wave positive rail DC portion (500 milivolts peak to peak... very high frequency... 11 miliwatt disturbance) may feel disappointed and may lost the interest in the amplifier....will understand have a defective thing... this is the way some folks are, and they are almost 50 percent (in my imagination) of the total ammount of audiofanatics, audiophiles, audiofreaks and other maniacs.
A capacitor, a big one, placed from the second VAS to ground will be understood by them as something that would destroy the amplifier performance (when did not!)..they also will not feel good having that...in the reality, my point of view, this will slow down their expectations about the amplifier, the amplifier performance have not slowed down, nor the simulations nor the sonic performance.
For these ones, the Dx Blame ES is something should be trashed... they will not be happy.....my position, that will never change about, is to say clear what has strange on it, to allow them to know what they gonna build..for those, maybe, the ST should be a better option.
To the others, that wants sonics, wants magic and outside earth lovely sound, unbeatable and unmatched.... other style of guys, a sort of guys that are not bothering if their audio amplifier electrons are wearing shoes left foot and wearing boot rigth shoe.... these should take the risk of a non guaranteed amplifier, and build the Dx Blame ES.
The decision to open the Dx Blame ST was the best decision i had these last years... i am sure i did the correct thing...now the criticism guys gone...thread is peacefull, only builders and friends landing here... created a group of ES lovers that will produce Dx Blame ES and ST board including both options (or i will be against them... ES and ST boards already exists and does not need another official one.... ES and ST options does not exist and needs an official option offered).
Curiosity will make people try both options to compare, as the talk to change from one to other are just details, a couple of parts to be removed, increase or included...so...people will realise by themselves what i am repeatedly saying:
- "perfect technicall decisions does not guarantee, always, awsome sonics...usually happens the opposite... there are exceptions, of course".
During these 50 years or research and huge learning ( i am very proud of half century experienced man i am... even if i was stupid, all these years should made me someone that know something).. i could be testimony of several over designed amplifiers, using V/I limiter and other styles of protection and sophistication sound bad... also i could not face simple ones sounding bad...so... simple is more guaranteed.
Another board should include the ES and ST options, room of them and indications for them in the silk screen...over or below the board... this is my demmand to give folks my agreement and support..because we have already official boards to the Dx Blame ST.
What i am asking.... please, include the options to Dx Blame ES and Dx Blame ST..this will justify a new official board and will void my demmand about.

Carlos

I have been asked:
"Rudi, what is the preferrable AMP - BlameES or BlameST - for Classics, for Rock, for voices, for chilling music, ....?
You can judge, since you have both the BlameES and the BlameST."
This question is hard to answer - no, it is not at all!
Both AMPs, the BlameES and the BlameST, follow Douglas Self's AMP design of the "Blameless" AMP.
Their schematics only differ in some "theoretical, technocratical" aspects: changing some capacitor values here, introducing a new resistor there,
leaving out a component, contributing to stability, but the principal design: VAS, CCS, Bootstrap is common to both.
So: what is the "magic" behind the DX Blame sound?
Can the sonics be tailored to somebody's needs (see above)?
Yes - it can! - I expect so at least - allthough I do not have yet any experience with this aspect myself.
But reading some evaluations of Pavel, ....
I (much better: the "DX Blame team" !) am currently very busy implementing a Universal DX Blame PCB supporting both
the BlameST and the BlameES on the same PCB.
Many greetings to Mr. METAL - are you awake right now?
I want to keep this thread "fascinating, exciting".
I guess (am sure) Carlos will respond before I do.
Best regards - Rudi_Ratlos

I do not only have both the BlameST and the BlameES, I tried different power transistors on them as well as you can see on the images:
Both the BlameST and the BlameES follow Douglas Self's concept of the "Blameless Amplifier", described in this article: Distortion In Power Amplifiers
The "Blameless Concept" offers very rich and detailled sonics, very smooth in the heights, in comparison to AMP concepts that emphasize dynamics for example.
Maybe you can even call this sonics "warm".
My preferred big SANKENs (2SC2922 and 2SA1216) offer to this AMP-concept very much trebble, flavour and emotion and contribute to my personal musical taste:
voices, smooth jazz, chilling music, ... no metal, no classics.
The TOSHIBA's SC5200 and SA1943 that I listened to for some while have a less warm sound, lacking a bit of the trebble of the SANKENs.
I would also once like to listen to On SEMI's MJL21193 and MJL21194 or even to their MJW0281A and MJW0302A (hard to get).
Carlos will tell me - after taking a look into the datasheets - if the On SEMI's are applicable to the DX Blame (I think so).
I - for my part - am absolutely content with the DX Blame sound powered by the big SANKENs, maybe Mr. Metal whose musical taste is different
from mine will use one of the On SEMI transistors.
The initial question was: "Which revision of the DX Blame - the BlameES or the BlameST - shall I take for which kind of music?"
The official answer will be: "Take the BlameST" (big grin on Carlos' face - my personal answer is another one, he knows), try at least 2 pairs
of output transistors, the TOSHIBAs and On SEMI's (begin with MJL3281A and MJL1302A) and take your choice.

Yesterday, 08:03 PM I was playing dead. You are aware that selecting the components, drawing the schematic, and checking errors back and forth was not easy in the last couple of days when I went to work awake placing components to see how things look like.
I think we will call it Dx Blame ES/TS. Dx Blame Universal, not Dx Blame US, never indeed, US stande for many meanings, no need to confuse others. Pick the one you like, but not Dx Blame US. I think Dx Blame ES/TS has a better notation for what we are doing here.
I am placing components, laying out tracks now, decide to move this component there, that component here, then go back and rip all tracks, then route again, it is not easy at all.
This thread is still it is fascinating, every thing - hopefully - will be fine.
