"Just good enough" and even better than "just good enough" is available as a kit, at a reasonable price - less than what it will take to develop such DAC, either by one person, or by a group.
Anyway, you should be an excellent anti project manager...😉
i hope it succeed if people spend less time about auto justification, personal attacks, defense about its, want to have the last word and beginn to think collective not in the sense to be the prophet of a catastroph !
And also not capture the attention by watering down the technical inputs by reapeting always the same things and fears and fill in the post of no usefull content or anti dynamic all along the thread. People just don't care to know who is right or xrong, it is just go, no-go ! Here we start this new side of your Original Question at 74 000 views and have never such reading : near than 6000 in less one than month ! It stay 5 months and people spend time to be carefull and live in the fear ! It's very descouraging.
I suggest fellows have now, please just technical inputs and "management" inputs for the rest of these humble project around a good synergie I hoped to be massive and collective.
We stopped two pages above at : Has Vanofonk given the name of its software or the acess of the design for non commercial needs to advance ?

I do not agree, I think Mr Joshua_G's comments are logical and NECESSARY.
Remeber: the objective has changed.
This will help keep everyone more focused on the "reality of the new objectve".
All that is needed to create a fairly decent TDA1541 based Dac is already collected here:
- References
- Links
- Collection of documents at linked hompages (some quite comprehensive)
What Mr Joshua_G is merely stating (as i have understood it) that this is only a small part of the whole process.

But writting once is suffisant...we are not fools, writting ten times the same is boring and antidynamic ?! I don'y forgett anything...I agree with the focused objectiv of AudiolapDance.

Audiolapdance,
I don't know if you need help to work on the Vanofonk files and Eagle soft ?
but I ask help here if you'll need :
@ fellows :
Any gentlemen with a little time free please to draw modifications on an already existing PCB ? Many inputs are known and were given by T. Loesch.
This is a collective work (a try to do it...) to improve already existing core board for TDA1541 in a hope to print it a collective GB if possible or share on a printing web plateform. Work is shared for free in a non commercial goal for DIY fellows to have a "good enough" TDA1541 kit.
If some people have try some existing commercial kits from EBAY, testimonies are welcome. But we saw most of the time than contigous ground never exist or than smd design were bad or than data signals were crossed with PS signals sometimes !
Thoses last threads are a trial to improve the existing as re beginning from craft has been gived up.
thank you for sharing 🙂 , this is in a non commercial goal to have something good enough as ref branded dac around tda1541 are > 1000 euros (ECDESIGNS, AUDIAL, AMR). It has been noticed for whom has money than it's not a bad thing to buy such device as DIY alone can be addictiv and more expensive at the end.). Life is short we never suceed to do better than those specialist, buy if you can. Here is a try to have a midle quality way for maximum of diyers.

Indeed, you understand me correctly.
Verbal fights and resentments of some people who don't get me correctly are still going on.
That's part of nature of open forum.
I can believe it so. You are the first at this game and very agressiv and you talk about resentments😱 : re read yourself... you also use lies and partial pastes. And it's always about you at the end! And finally nobodies cares but you continue always to brake the others... ever and ever ! You don't care as you have already a device to hear. No resentment from me but I am not blind about your methods. Please stop !

You have stated clearly your opinion, you can move on now. Even if I have john brown sd player, I would still like to see a good TDA kit. You dont want to be involve, fine. You dont see the point in a project like that becaus there's already DAC kits using the same chips, fine.
If you cannot see how and why your irritating off some people in this thread, your are completely blind.
And you dont seem really positive about the whole project.

And playing the false victim add nothing Joshua. If you want to play collective and not bring back all to you all the time, rewrite the truth to have the last words, people may be will be glad to read from you the kits you bought before and which you find good enough or not as we say there are none several threads above.... are you able to give something positiv and real efforts?
But now we have maybe a process (or maybe not as it become disgiusting and bad faithed):

You play the provocation, i think it's a game for you. You just don't care. Did you see any moderators input ? Do you look for it with escalation attitude ?
Again , let's come back to collective and technicals please :

While browsing through the homepage of TDA1541A, I noticed that this DAC design
desn not include Digital Input Receiver section! ouch!
Anyways,
I still feel the information on his website is very relevant and very decent.
Here is another VERY interesting implementation on NOS TDA1541. (I am sure you know about it).
Concertus Decima Digital [English]
But the most interesting part of the design is imho would be the output stage with a little bit of positive-feedback applied:
TNT1541 - diy zero-oversampling dac [English]
Fabulous.
Good Luck

Thank you alexiis for the inputs. Did you have the link on your PM i gave you about non feed-back emitter follower reg ? i hope you can say if you try more usefull or better in the place where it's discussed.
Yes Alexiss, but do you see the adress to the powersupply section I gave: as I can not manage attachment in PM: "non feed back emmitter reg". As i promised you a shematic it is in this section with an open thread.
Here it's not the place as we are focused now on T. Loesch inputs.
Here it's not the place as we are focused now on T. Loesch inputs.
The schematics you showed is very good and can be easily applied to all the TDA1541 voltages: (+5, -5, -15)
It can be improved upon a little bit, but it will work fine the way it is drawn.
Any suggestions on power supply is valid, and should be considered.
I strongly suggest to follow the drawings of the TDA1541A (call him Mr. X)
His PSU design is based on Mr. Nazar's Capacitorless PSU and is very sound.
His overall design is good and could be used with sucess.
Your problems at this stage are:
- Finding and asking Mr. X to provide the pcb files,
- Modifying the pcb files to suite your desing objectives.
- Building and testing of the modified pcb,
- Finalizing the pcb design.
Therefore your main issue that should be adressed is:
- to find a good PCB designer.
- to find a Design Manager.
Finally I would like to add that "critisism" is always good and necessary.
Being in the company of individuals that "agree with you" on everything will only lead to dreams unfullfilled.
I personally disapprove of verbal attacks on each other,
Remember, what Mr. Jashua_G is stating is what I have been saying from day one.
But it seems you want to go on. That's fine.
Once again:
I just want to help you find and build a good platform (not too much modifications and changes)
so that you get to the final result fairly soon.
Otherwise it will take forever = a lot of money.
Remember: Winners take the negative and turn it into positive.
Do not get upset when someone does not agree with you.
Any input is a good input.
Cheers.

The analog stage that i referred to is a VERY GOOD one.
It uses a highly underestimated and old technique to provide gain for the output stage.
It has better output characteristics and (of course) lower PSU Voltage requirements than most tube stages.
This would be for those who do not want to get involved with tubes, high V:s, etc.
Otherwise I would recommend:
- Mr. Fikus' Output Stage "Audio-Note Style". (There is an attached pic on earlier posts)
- Gomes amp is also fine, although much more complex and difficult to tune (believe me).
Output Stage "A la Fikus" is infinitley simple and pure, so pick your choice.
If you read the earlier posts that I have submitted (study carefully):
I recommend very much against:
- complex,
- multi-stage,
- or IC based output stages (using very modern chips).
These are not suitable for diy:ers and beleive me, they are not "that easy" to work with as you might think.
Cheers
