Hi Guys,

I'm always up for a great project. I'm in for a SE Dac + PSU, updated the sheet.

Thanks,

PJN

Hi all

The GB is going on the right way, but we perform do better.
Glad to see that Jean-Paul has posted some good informations
My V2.6 ES9023 is now improved with 2 BlackGates in C10b & C32 positions.
Result : deeper bass (yes it's possible) and more global definition in the soundstage !!!
The output level gave a strong & clear signal, my pre is now on -30dB.
This board is a real bargain, can't wait to build a BAL version using V3 PCB.

Where did you get the BG and what grade was it?

 

[grufti]

Phil, in addition to what grade BG, what are the values and voltage ratings for those two new caps?

For optical can I use the TOSLink module from twisted pair audio? Is any kind of input-output "matching" that will need to be done or just connecting the output leads to some place on the PCB? Any other TOSLink options?

 

[Ryssen]

PS : Hope you'll be delivered soon.

Got the parts today!

Hi Ryssen and All

Ryssen
Glad to see you've finally been delivered
Enjoy your built, take your time, read the Build Guide too.
BTW read the EU Parts GB there are some hints about parts.
BG went from a friend old stock, he picked up two units for me.

BlackGates : NX HiQ 47uF/6.3v at C10b + 0.47uF/50v at C32
They seems to be available here : http://www.partsconnexion.com/capacitor_ele_blkgate.html

TP TOSLink module needs to be fed by SPDIF Data stream & requires min 5v external PSU as it has a 3.3v onboard reg. It's just a media converter Cu to Optical Fiber.
No input-output "matching" needed, just connect SPDIF from ES9023 to TOSLink.

They seems to be available here/QUOTE]
I asked them and they are out of stock,
They recomend the ELNA Slimic or serafine as an alternative.

 

[korben69]

Can't understand, they are online, seem to be available and finally not

Take time to taste your actual caps before modding

But I cannot find any WM8804..

Åke, check carefully inside the bag. I "lost" a few parts inside the bag, because they were stuck to the tape. Once unpacked, I "lost" at least one on the circuit board where it glued itself to the flux, but in the wrong place. Fortunately in my case none were ever really missing.

Please count me in. Updated the sheet.
This would be my first DIY DAC.

Now I searched everywhere,and there isn´t any..

Hello !
About WM8804, I've bought these :
eBay | WM8804 S/PDIF Digital Interface Transceiver 1pc.

SSOP28 isn´t the right package,it´s SSOP20

 

[korben69]

But I cannot find any WM8804..

All kits have been checked twice before sending, but I could have made a mistake. PM me for details and solution.

I'll take one single ended PCB + power supply. I'll update the sheet.

 

[korben69]

Hi Algar
You're welcome, maybe with your input we'll reach 200 units reserved !
Hope you'll enjoy building & listening to this DAC.

I cannot edit the google page. What is the trick?

 

[korben69]

There's no trick inside Algar
I've added your nickname for 1SE + 1PSU.
Do you need Parts and ES9023 ?
