Not off topic at all! This thread is about 1541 kits or PCBs and you're got a fine one-- very well done PS decoupling and DEM decoupling.
What file/drawing do you have for it? Could we convert it to a gerber or something and get some PCB made? And you've been using it for 2 years so we know it works!
Cheers,
Jeff

Thanks for the kind words.The program i've been using is TINA. Converting them to gerber shouldn't be a problem but im not sure where that particular design is on my computer, ill have to dig for it.
Another design i've been working on also in TINA has the CEN IV and 2ma current injection built into the same board, ill attach the layout to see what people think. Bare in mind that i've designed it in a way that makes it easier to drill holes by hand, so the vias are covered - but i guess that can be easily changed if need be.
Ill also attach a measurement of the CEN outputting a 10k square wave in my current setup. The Red is out of an F5, the blue is the CEN.
ALWAYS MORE PEOPLE SHARING
Hi Ryanj,
We have now one more core board and some diyers are walking towards concrete solution alone or togethers.
Methods for printing pcbs can be shareded here via pdf attachement or can be converted as said via other diyers as said above.
Hé, c'est super !
Thank you for sharing
PS: I talked about Peufeu & ps low noise experiment but didn't give a link. Here it is : http://www.diyaudio.com/forums/solid-state/253390-experimentations-regulators.html.
Well new things are coming with Andrea Mori and mr T. about PS, existing design are always valid aswell if a smd coreboard stay the goal. And Peufeu which works a lot on the TDA1541 also has a ps design in the link above (short & interresting reading). Merci Peufeu, si tu veux nous rejoindre yo are welcome dans notre sympathique petite utopie

Here's the place vanofmonks was using to get PCBs made (seems good unless someone else has a better suggestion):
OSH Park ~ Welcome
And here are the design submission guidelines for OSH Park:
-----------------------------------------------------------
File submissions
Eagle CAD
We are currently processing uploaded files with Eagle CAD version 6.5. If you are using a newer version than 6.5 then please contact us, or generate your own gerber files.
Gerber CAM files (in Zip format)
Our site knows the default naming scehemes from many PCB design packages, however if you have problems, this is a naming scheme that is known to work.
If the website doesn't understand the default naming scheme of your PCB design package, please email the zipped gerbers and the name of your design package to support@oshpark.com.
boardname.GTL Top Layer
boardname.GBL Bottom Layer
boardname.GTS Top Soldermask
boardname.GBS Bottom Soldermask
boardname.GTO Top Silkscreen
boardname.GBO Bottom Silkscreen
boardname.GKO Board Outline
boardname.G2L only if you're uploading a four layer board
boardname.G3L only if you're uploading a four layer board
boardname.XLN Drills
"boardname" can be whatever you like. Only the extension is important.
Design Rules
You can download our Eagle DRU file if you're using Eagle CAD, which will verify that your design meets our design rules, otherwise here are our specificiations:
6 mil minimum trace width
6 mil minimum spacing
at least 15 mil clearances from traces to the edge of the board
13 mil minimum drill size
7 mil minimum annular ring
Processing Errors
If you've tried to upload your design to the site and have been given back an error message that you don't understand then email us your design along with the error message that you received and we'll do our best to sort it out for you.
Common Problems
Missing layers
There are a lot of EDA tools out there and not all of them are created equal. If you're uploading Gerber files generated by your package then you may need to rename each of the Gerber and drill files to match the naming convention above. If you have done this and are still having errors then please contact us.
Documentation Framing
Sometimes documentation framing is exported to the Gerber files by accident and will trick the system into quoting you for a much larger board than you are actually trying to build since it can't tell the difference between the board and the frame.
"Unknown Error"
If you receive an "Unknown Error" then something bad has happenned on our server while trying to process the file. We really want to know about this, please send a copy of your design to us to take a look at what happenned.

Here is one more option gentlemen.
Raised by GaryB and inspired by Ceglar (on the charity course) I wrote to Pedja yesterday and the good news is....he has agreed to do it!
Choices:
1)Full DIY kit - AYA II PCB with parts (TDA1541A chip tbc) with min order of 5-6 kits.
and/or
2) Just the AYA II PCB (min order of 30 to 40 boards)
(Notice that both choices come with complete assembling information, but understandably no building support included for the PCB option from Pedja). Please also be told beforehand to observe and abide to the copyrights and do not reproduce any material supplied should you choose to participate.
This should be a great start for a home run project as a core board where one can build on top other daughter boards for his own choices of input and output schemes, and for any modifications, etc.
Would like to nominate Eldam to manage this group buy as your enthusiasm and sense of humor guarantee that you will make this GB project a success. (Please use your charm to negotiate on the pricing, merci!)
Oh... I am a happy user of my Model S dac from Pedja and my hifi buddy Welborne has Thorsten's modded Satch dac, we both enjoy the TDA1541 sound and hope very soon you will also enjoy it too from your own diy efforts.
Best regards,
Cheung

I might have sounded definitively above, but its really up to the consensus of you guys ..whether this option should be taken or not. I do urge you though to look at what Ceglar has expressed earlier..it is not easy to make this dac from scratch...and this AYA II dac has proven itself to be a fine one over the years.
Wowwww: Great initiative CFT, thank you for that...we are stronger together guys to move mountain ! (Chineese proverb : if your obstacle is the Ocean, move like a moutain !)
Pcbs will be more simple to manage than devices ! If devices are choosed money can be sended directly to Pedja because VAT and all those things & devices sended by him if he is ok for that !
I'm agree to manage a grup buy for PCBs sended to me. My english could be enough for that I think but maybe not for details discussion with Pedja before...
Why not a AYAIII or a more recent (not the last of course?) ? Pedja disagree but the AYA II ? I ask because many seem to pocess the AYA 2 already and tweak it. But the aya 2 respect the "good enough chart " which is great.
Could you before before organise a standalone thread with a poll in a good "americaglish" to present the idea and give the link here please for people to know it : we had 11000 readings already... the trip begann at 74 000 readings if my memory is good?
We need to know how much people, pcb or device, usb or spidf ? Can he provide the TDA or is it as here : only for the owner of a chip already ?
Then give to Pedja the number of people interrested. Then Pedja give a price and for respect to him and his business i think the price have to be given only to the approval list by PM with the promess they don't speak about it on the forums. If people of that list are ok, we give to Pedja the final number and Pedja if interrested give a go or a no go. Then I can manage the GB and share the final price and list with Google forms (I will learn it) tools.
Are you ok CFT for manage those poll pre phase and ask with you rmore correct language before to Pedja wich more recent pcbs or devices could be included if possible? But ok also for me for the AYA2 : "good enough"?
Or something else here for the poll : sharing time, collaborative : but here if you go, you are of course on the list of interrested people for Pedja GB.
Thank you Mr Pedja if you read us for your openess and sharing mind attitude.

Ok, just understood one thing just now because my bad english : option one : tbc : to be confirmed (for the DAC chip). this is an important detail for the one who don't pocess a TDA. Most of us has one here, but if dac chip provided maybe more people could be touch. Pedja would say us if we are able to provide a number of interrested people !
Waiting tour answer CFT to my proposition you organise a simple little poll standalone thread near this one, or of course an another fellow if interrested to write the poll on a standalone thread.
@ moderator : does such a poll need to be writted on a GB section or is this section ok (or in this thread ?)
thank you

AYA 2
This is not me who can decide for others. People who want option 1 or 2 should fill in a form in a poll or an incremental list in a new thread to show their interest before having a price to have a final decision after.
My understanding is the AYA 2 (USB + spidf) seems easy to do (no smd parts but USB input... don't know !) for a majority of diyers. I will be worried about the 3 black gate caps as the AYA were optimized for a subtle flavors around the Layout AND the components (allen bradley resistor if i remenber, BG N for output caps...). Description here : Products archive
But maybe doesn't matter as it is an exceptional operation... remenber : "good enough" ! I surmise the AYA 2 without the Black Gate to be far more better than a "good enough"
But If option 1) is the one people want, we will ask to Mr Pedja Rodric what is the parts provided. If Option 2 (bare PCBs), we will se if people want a GB for the parts with the BOM provided by Pedja. But here I'm talking in the silent space...
5 persons mini for option 1) , 40 for option 2). I'm ok to manage the GB of option 2) for pcbs and if the parts cost is > 65 euros (everybody has free shipment at Mouser/Digikey).
remenber this is a collective project... the development keeps going on here in // also if people continue to share ! But all is Music as Pedja says and for music wee need to play... together :
We need someone to open the pol or an incremental list to give a number of people to Pedja and ask the cost details can be asked to CFT who writed to Pedja for this gentle proposition !

Hi,
This is a shot in the dark as a lot of time has passed... But does anybody still have a copy of the Pedja Rogic 1541A DAC REV 1.1b documentation? I was digging through my stuff and found the PCB and transformer that I bought for this project. Unfortunately, I can't find my documentation. Can anybody help?
Thanks, Daniel

Sabbu DAC introduction
Hello to all, this thread is very active and goes into much detail. Have read many interesting posts by Jean-Paul ( fan of : "Still blickt der Himmel mit all seinen Sternen auf das Gewühl der Menschen auf Erden herab" ?). But as a novice I am looking for some basic informations regarding the advantage of a digital versus an analog board. I am considering amps and XO by ESP. Could someone tell me what advantages a digital board has ? How can you integrate a crossover into the unit ? Would I need 3 stereo-amps for a 3-way speaker ? Is it software-programmable from a PC ? Where are the elementary informations ? Can the unit still be ordered ? Thanks and have a nice day, Marc

I think it's not really the good place Chano for that : you have to open a thread IHMO.
Here we talk about a specific dac chip TDA1541 for a stereo device or board (non active one for speakers).
Up : for a fellow to manage a poll to see go/no go for a GB with Pedja Rodric (pcb with parts or bare pcb + BOM list)

I am in touch with Pedja now and will post once I have more information on pricing and description on both choices. (Then Mr. Eldam we need your help to set up a GB if this option is good here).
My understanding from Ceglar's system is that AYA II is an excellent core board consisting of nice power supplies, layout, and grounding, etc which has taken years to perfect; by itself its already a nice dac.
For those whom are more technically inclined, several modules of your choice could be assembled into this dac to replace the existing functions:
1) your own usb receiver/spdif section, or i2s tabs, IanFIFO, etc.
2) you favorite output buffer (tube, opamp or discrete, etc), and bypass the opa861 stage with a passive I/V.
3) add the dem sync
4) optional: Run it either in simultaneous mode (pcm which needs slight reconfiguration) or i2s
More later.

For the pcbs...i can manage option 2. Come back with the BOM or the price of it also to have an idea of the total cost. Trafo is a complex one and don t know if exist on shelf.
for the moment only me and Audiolapdance have been showing some motivation.
I think AYA 2 is an excellent DAC as Pedja is a lover of music and spend many time with optimisation (parts, layout...).
And folks :no tubes, diy friendly for most of all, no smd... I can't believe we are only two now !
We still need someone to make visible & organize the poll between 1 or 2... I can not do all alone !
When Pedja will be ok, CFT can you send me to me and Audiolapdance (the mails exchange with Pedja with info and contacts as well... )
thanks CFT for your kindness
