I have a pcb for a clock from ELSO WKAK on the forum but i have never used it. Is that from guido? Is it the same person?
Guido Tent and Elso Kwak are not the same person, but they have good ideas about clocking and reclocking the dacs 😉
Their solutions are not the same.

D1 boards
Hi Ilias,
i´m interested in one balanced set of the D1-boards too (maybe two)!
Cheers Axel

The D1 I/V Boards will cost around 12-15 Euro and the power supply boards will cost 7-9 Euro each.
It depends really on the number of boards that will be ordered.
Do you also need a power supply or not?

Hi Promitheus ,
I am interested by the whole set of boards , if you can give pdf and schematic to mount everything

is it the case to set up a group buy?
Dear Guys,
i really don't know how this could be done, as I never managed such a thing and by now i have no spare time to learn how to do it (I'm working from 7 am to 9pm. hope to change ASAP!!), but proabably a group buy could be interesting.
As already said i'll be in .
Ciao

I want to thank all those who have ordered. I still have a few pcbs left so if anyone is interested please mail me for more information.
For those who have already ordered I am gathering the parts they want and I will start sending everything end of next week.
Stay posted.

hi Promitheus.
i've sent you the order form, but I'm still waiting for a confirmation of the grand total+ shipping.
let me know, so that i can arrange the payment.
Thanks.

Hi there pamaz.
I sent you an email on the 26 of Feb.
Anyway I sent you the email again, so check your email.
You got email !

I will be getting the parts in the next days, so I am very curious on how everything will turn out.
I will post some photos of the new boards and parts as a small hint of what they look like.
For those who have already ordered and paid I will notify you as soon as I start sending the parts. Thanks for the support and the very nice contact. I think I can send everything out next week. It depends on the delivery of some of the parts. I had to order them from different suppliers. It really sucks when it gets to ordering things. Anyway...
The communication with other diyers is what really makes DIY fun.
so keep posted I will be back with news.

Hi everybody,
did anybody finish the PCBs yet.
I would like to know if all went ok.
Greetings Promitheus

up and running
Thanks Promitheus. The thing is working but still i don't want to judge it as it's assembled with scrap components, just to understand its potential.
At this moment i cannot understand where the lackness of bass that i can hear is coming from the Digital side of my converter or if it's a signature of this output stage.
Probably a mixture of the two !
Bye and thanks.

Mine is assembled and electrically tested. Not yet connected to a Dac.
A few remarks: the PCB holes in some occasions (ie the rectifier and output cap) are way too small. Apart from that a nice PCB.
Cheers

Re: up and running
Usually the op amp with great feedback loops , pumps up bass and high ( as a perception ) and it takes more than a biscuit to feel a clean and extended bottom end
Probably for the lack of feedback , but the bass is all there . BTW with a great clock generator the bass changes its face.pamaz said:

Hi,
well a few holes on the psu are smaller than planned, only fractions of a mm.
What kind of clock do you use.
I am using the Elektor DAC with upsampled input.
Do you think that it would work better with an external clock?

Generally yes .
