I have visit your country during the nigth and i have entered your Metalic Labs
I am very honored to have you in our group, using Metalic Laboratories to make nice service to our Dx Corporation, German Division - Rudi Oberkommando.
Was nice to see you, to listen your voice and to discuss audio electronics with you..you're very welcome to the Dx Corporation, and seems will be our main layout designer from now on...will compete with Sakis Petropoulos from Dx Corporation - Greece..maybe you both will develop different circuits.
I am entering a new forum, and will not abandon this one..i have gratitude for this forum that helped me a lot..but will develop other designs there.... as i know the owner and moderators and there no one will bother me because will be kicked out in a flash.... i would like to invite you as also my good nearby friends too..not to leave this one..the best one..but to help into the development of that other one too.... there i will show folks how to design amplifier..will explain in details.

my gosh, do they know what they are letting themselves in for if they give you free reign
😀
The main difference will be that i will not accept people criticising before they
listen to the amplifier.... alike my small son does...he does not eat tomatoes and he said it is no good.
Then i ask him:
- How can you say it is not good when you have never tasted it?
Got it dear Bigun?.... i am sure you got...some guys evaluate watching schematic or calculating....when sound should be evaluated listening.... we have sonic signature that depends on topologie..but audio quality..only listening.
The previous post shows the forum owner..as you can see..the guy is with me..and said i am free to go ahead...i told him what i dislike and he agreed with me..so..we are "tuned".. some friends... more 5 or 6 will be with me there too..and this is enougth.
I would like to have you there too Bigun.... new forum, needing active folks..people that do things, open thread, publish schematics..there you will not see advertising... it is non commercial, for a while..the owner is rich enougth to keep the forum running without advertising or help.

my son is exactly as you describe - he can tell the taste of food just from looking at it !
I will pop over and see the other forum some time. But so far I like this one and it takes enough of my time. There are forum's where the owners don't even allow you to talk about other forum's let along post a link to one. That says a lot about the quality of this forum. Some advertising is OK, but we're kind of at the limit here for my liking.
I am starting to build again. It's been a long time since I had time. Usually I have only some time and energy to play with Spice. Now I am going to make some modifications to the TGM1 and the TGM2 amplifier and see how the sound changes. Enough time has passed that I can approach them with fresh eyes and it's the easiest path to the soldering iron.
But soon after that I will have to start a new project. The TGM may be the only amplifier I build with LTP on the front. The next one will be different.

I do not mean to leave this forum, the best in the world to enter an adventure
Not alike a marriage..that we have to finish the first to start the second.
The idea is to visit, to help a forum that is starting.... very empty, needing some folks to create some "noise" and start projects there...but never abandoning this one.
Of course, after your ressurrection..ahahahahaha!...as your words seems to me you are dead tired.

yes, it's been tiring at times, the sudden upturn in the economy has made the day job more challenging since last Fall, in a positive way of course. But it has meant little time for hobbies.
Today, the bench was cleaned off, parts found and stored away. Soldering iron is now out in the open and TGM boards and power supply are gathering for a reunion. (The economy is still doing OK, this isn't a sign that things are about to go downhill !!!)
The simple TGM1 (a bit like the DX perhaps) needs attention first - OLG falls off a bit early and it can get a bit muddled when I crank up the volume. It sounds nice all the same but TGM2 is so much clearer (a bit like your DX Precision I believe). The TGM2 needs some work to bring some of the warmth of TGM1. I don't think it'll require more than a couple of small tweaks.

I hope you manage to have some time and find some motivation to go on
You are good, have passion, is a nice guy, and this forum has a lot of things to explore from your person...you have a lot to give, a lot to contribute.

METAL has done a great job in the last 2 weeks, spending lots of hours on translating the DX Blame schematics as they are published
on Greg Erskine's homepage into EAGLE schematics.
This is the result:
I am now very proud to reveal the first 3D-image of the DX Blame PCB, based on EAGLE's .brd - file, which took METAL another 1 - 2 weeks to produce.
While we are in progress of verifying, optimizing - a never ending iteration - the PCBs design, the components' sizes, the look of the PADs -
I am asking myself if it makes sense from an audiophile point of view to even include the PSU for each channel on the PCB.
This is how the PCB would then look like:
In the center, painted in light-orange, the DX Blame circuit METAL designed.
On the left- and right-hand side of the AMP circuit the PSU for each rail and at the bottom the transformer-connector and rectifying diodes.
The size of the complete board incl. PSU would be 190 x 95 mm.
Apart from the fact that the board is that large: makes it sense to include the PSU on the same board as the AMP?
Is there any physical drawback when doing it like shown?
I do not like a "modular" approach very much, since modularity normally ends up in a lot of boards and a mess of wiring:
2 AMP boards, 2 PSU boards, 2 speaker protection boards, ...
What do you think?
Your advise is welcome.
Best regards - Rudi_Ratlos

I do think the same....modular represents a lot of wire, a dirty messy construction
But, watching by another point of view, supply in the same board looks cheap commercial product, reduce of costs... increase of profit this way..no connectors, no good shielded cables..something alike very old things we could buy down the seventies and eigthies.
In my mind, separated boards or a single board will not harm the audible performance, so i have anything against one or other.
But, i feel, people, now a days, is already using separates, despite seems this is changing, some folks are building integrated your way.... a matter of taste...i like blonds...and i prefere not too much decent women... decent for the society only, decent outside home and depraved inside home is much better...others, thinks different.
Nice work from your group Rudi,
Thank you,

Carlos

I am glad your group had courage to stop when found good enougth
not perfectionists and having a good leader...you Rudi.
Someone must say "Stop!" this is good enougth, or people will never finish, always making improvements that results in a "never ending layout design"
Each time we observe we can find things not perfect...we can change today and tomorrow we will find another thing that should be changed, moved....when we really find it is ready..then we show to another biologic unit (another man or woman) and the one point things not good.
Observe the image...crowdy there..unballanced image..ugly to my eyes...gravity center is not fine... if this is left to float in a swiming pool it will sink because too much heavy left upper side.
Then if you change that..other will find another thing to change.
Good that you decided..this is the final one and ready to go...this is progress! decision!..courage!
about these things i could see..we all can see this..a never ending criticism we can do...means image symetry, image ballance, distribution of weigth, gravity center, how good it may look, harmony in the image, class.

Carlos

Hi Metal,
I have attached the 3D model of the TO3P devices that goes with the 2SC5200/2SA1943 library.
Remember, Carlos does not like Eagle, so you should look for another CAD program to produce DX amplifiers to keep him happy.
regards

Not really, Eagle is fine... i cannot stand to learn the use...i do think it is
hard and complicated..i really have preference for easier things..tools to make my life easier, not to complicate my life.... maybe i am lazy or stupid..but i really think it is too much waste of my time, when others loves to make boards using eagle, and i would hate to do it.
I love the way they did..i am following step by step, receiving images from them, in direct contact with the layout designer, Omar....he is also in the other forum i am too... diysmps.com
What i intend to say, is that we will never finish... art work is a never ending task Greg... you finish and them you perceive that something can be even improved, removed, reduced, or have position changed.
That needs courage and decision to say..it is good enougth... Stop!
You really knows something about me, but i really do not think you know all of me dear Greg... i am already super happy with Todd Johnson job...i think what he made is unbeatable, even for Eagle software...this is another option, German group is playing, having fun..to me this is an advantage..one more, sligthly different board... needed one, because eagle can put out the needed files accepted by factories to produce boards.

Indeed, everything is arbitrary, can only mate with newbies because his thoughts deviate too much from common sense (which has nothing to do with popular wisdom).
Eva, you raise a very good point which I had not thought about. Carlos serves a very valuable service to the newbies because he provides the stepping stone enabling newbies to go from being novices, climbing through the ranks to higher levels. Most experts just can't be bothered with rank beginners, so they would just fall by the wayside. We all outgrow our teachers eventually (hopefully).
Often a simplistic, practical approach is more beneficial to newbies to get them interested. This sounds a bit like the difference between a teacher and a professor.

Here you go Rudi & Carlos, C1 is changed/Replaced, I also added a couple of PADs for the bigger capacitor. C14 is smaller now.
For Eagle, it was the choice of Rudi that we use Eagle because he knows, a little bit, how to use it, he helped me in selecting correct components grids and outlines.
I and Rudi are thinking about creating a group buy, but we don't know how many are interested in Dx Blame project. We have to decide first, if the PSU is going to be included on the same PCB or not.

Very good folks..very nice.... excellent..parfait.
thank you Greg...i do not know what Eva told but i like your answer.
Group buy is excellent..but you should know, in advance, that this represents a huge work... try to visit Nordic (Nico Daniel) group by to the HRII and you see how this works and the responsability this represents.... look here and know, in advance, the onus and bônus:
http://www.diyaudio.com/forums/group-buys/108456-destroyer-x-amplifier-dx-hdii-version.html
AndrewT have complained..he said has bougth and have not received his boards.

Perhaps you have overseen that this is no longer a technical thread in which you can argue with Carlos about the concepts
and implementation of his "Blameless - AMP" design.
At this moment this thread is dedicated to small team of HiFi - enthusiasts who do their best and work hours and hours to produce
a PCB that will support the whole DX Blame Familiy (AMPs) and can be etched professionally.
Maybe even the resulting PCB will one day be made accessible to any DIY'er.
If you have something to contribute that is of value regarding the PCB design, the question: "With or without PSU" - you are welcome.
But please do not disturb the fun and pride we have while setting up our own, individual, professionally looking PCB - design.
Best regards - Rudi_Ratlos
