will have some modifications (will try of course), new input impedance, smaller input capacitors, different currents, increased driver current, maybe CCS to drivers, new adjustment to bootstrapp action, other transistors, your suggestion (also Andrew T) 470uf or more FB condenser
but the 330uF or 470uF cap is to suit the resistor values shown in the current version of ES.
If the March version has different resistor values and different DC blocking cap on the input then it will need a different DC blocking cap on the NFB leg.
You should not adopt a recommendation for this amp to your next design without checking what it will do to your design.
 
Rudi, because the heatsinks you bougth, i think we can increase your amplifier power

It is easy, some minor modifications, higher voltage transistors and condensers and new adjustment only..then you can increase your power to 120 watts rms in 8 ohms if you want.

The needed second transistor pair can be "arranged" in the same board i imagine, mounted side by side with the others, but cannot be the big Sankens for that.

Well, big Sankens maybe will survive to 100 watts rms output, these ones you use are really huge.

But you gonna need to order other transformers.

Just to smash your friend's amplifiers..hehehehehe.

I am bad!

Dx amplifiers, made by someone like you..audiofanatic, tweaker, a curious man

someone that goes trying, someone that is learning and studying, someone that is slow progressing, someone that makes several mistakes a day.

People, simple people like you....here no PHD, any post graduation, no graduation, no certificate, no College degree..just hard work, burned fingers and lovely sonics.

Join the Corporation!

Carlos
 
Dx Blame ES, some comments about bass reproduction

Of course, having the music a lot of bass, no doubt
the amplifier will reproduce, however, despite this sample
seems strong , i think the reproduction of a low tones is a
little bit shy compared to the Standard Dx, if the
Dx standard was the unit to reproduce this music, under the same conditions,
the speaker cone/ diagram would be almost be spitted out
from the chassis frame.

I think bass fanatics should not build this amplifier... despite it is the best i could ever listened to, i feel the bass really shy, and i use to say the real thing.

Here you have a 10 second sample:

@Wahab:

Are you really considering my "Little Susis"?
(Carlos: Only one post of mine to "destroy" your "Divine BlameES thread".)

...
PS : Rudi s near field monitors are awsome.
...

These "Near-field monitors" - called "Little Susis":



are the speakers (consisting of Dayton tweeter and Tangband broadband) a "new" AMP has to awake to life before it enters my living room.

Do you think my "Little Susis" are worth while opening a new "DIY-Speaker" thread, Wahab?

Best regards - Rudi_Ratlos

P.S. How did you guess they are sounding that beautifully?


yes, that would deserve a thread, they look good sounding
psychologicaly !!
germany is the land of high tech, yet rugged, technology!
the ones on the living room would deserve it equally,
if not even more..


regards,

wahab
 
I don't mind if you spend some posts discussing the subject

Rudi is building Dx Blame ES, also he built the Dx Amplifier, the standard one.... so... he is at home here.... 4 to 6 postings is fine, then we can return the main subject.

Rudi is also CEO from the Dx Corporation...and this Corporation exists in my dreams only...understand that as an audio Club.... the "Corporation" club, with everybody using the same "T" shirt.

If moderators does not enter to complain the off topic.... then it is all rigth to me... this is audio and forum friends having conversations, a very little bit outside the main topic, but still inside the global audio fanatic universe of topics.

Here one more audio sample:

Passion Andrew..this is passion!

Some of those guys are different than you and me...i am having, now a days, sadly, a very slow internet...my upload and download does not exceed 32 Kbps...this means a 300 connection.

In my country, and in special in other more modern countries, people is having 10 Gigabytes of speed.... so, they upload and download 1 Mega files during the space of time we flip our eyes.

So, for those ones, this is not a crime, and this is allowed to forum, each picture can be 1 Megabite size.

Carlos
 
Wahab,
what the ........ are you doing reposting someone else's near 1Mb download?

oops, sorry andrew...

as carlos is pointing, i ve got an internet/phone/tv 100mb speed bunddle for wich i pay a hefty 20 euros/month (internet providers are thieves by there). so i just don t realized that the files are that big...
 
the Forum rules tell us not to repeat and tell us not to re-post whole items.
A link to appropriate post would have been enough.
Those that are interested go and look, those that can't afford the bandwidth decide for themselves whether to download or not.
Those that don't need to see the pics can decide to move on.

Leave the decisions with the reader. Don't force them to download huge files.

And before DX chips in, I am not a Moderator. I am a respectful ordinary Member.
 
I think they have not ignored you Andrew...they have remembered

in my point of view they have remembered you in the wrong way, in the wrong moment and with a wrong action.

But, as this is a rarity, i will forget that.... same way people forgot me.

We use to repost entire texts, and this is an old practice that also use forum bandwidth...happening since the forum exists.... well, i do not like to be discussing what other people say..you see i usually do not do that.

Were are all those rules?... really this may be not in an obvious place..i remember moderators are 7 feet high, ask us not to use what the ......... you have used... but rules are not so very clear this way...maybe i have not found the text is detailed this way.

regards,

Carlos

Not where near Mr Carlos boards and components but at least its playing loud and no modifications . just as the 1.4c schematic.
we will wait the Final release on 28 march as promised .
I know that it look ugly but I couldn't wait to build this one when first time I read the thread .
will wait the final release to build with a better looking .
Thank you Mr Carlos .
Thank you Mr Carlos .
Thank you Mr Carlos .

. . .

Simple: The 220uF hooked to -in position is removing bass in proportion to the gain. If this capacitor value is larger, then it can quit removing your bass. :)
 
Yes...you already said that..i have tested, if you read the thread with attention

You will see i have made that modification and the sound does not result fine.

I have published picture, this condenser was increased to 820uf.

Try to read, then you will be better informed about what is going on..reading just the last post will result you gonna be lost and repeating suggestions already tested.

regards,

Carlos
