On this page, you will find the schematics and parts:
http://www.awdiy.com/index.php?page=miniclock-schematics-and-parts
The parts are easily available if you have access to suppliers as Farnell or DigiKey. The only problem is that you sometime need to order 10 or 20 units of each parts to get one. ;-)
TCXO need to be ordered to dedicated TCXO suppliers as Selectronic, TentLabs or diykits.com.hk.

Nothing really important. Most things are cosmetic changes.
- Corrected 2 times C36 on the schematic (second was C37). Was ok on the pcb.
- Added complete references for C21 and C23
- Updated C34 to 10SH68M
- Added a BOM file with complete suppliers and Farnell references (and some from Digikey)
For C27 and C28, base is still Tantalum 10uF but you can put BG 47uF PK or others as a try. For R5, I used an expensive 0.1% very low ppm found in one of my boxes but a regular 21K 1% 100ppm is ok as well.
May be parts will change again with diyers's feedback.
I also calculated the parts price for the PSU. It's around 100€ with VAT for all electronic components.

I tried Newark and I can not find the EPCOS
B37982-G5104-M listed in the BOM as
C35-37 100nF 50v Capacitor X7R PCM 5 B37982G5104M 1200403 1
Well I can find it if I order 4000 what part number did you use?
Would it be possibe to use WIMA - MKS2 0.1UF +/-10% 100V instead?
Or something else all together
Tight!....
If I move the DSP card the memory card reader gets useless.(Not that I have used it..)
Or have the trafo outside.
Or have the trafo where it is in pucture,and move the PSU card to other side of DSP.I think it´s better to have the PSU card on otherside than tarfo,I mean near the inputs.
Suggestions..
Edit: Do I benefit in using the Tentlabs XO clock pcb or just use the tentlabs christal?
An externally hosted image should be here but it was not working when we last tested it.

Do you need an hammer?
Don't forget that personally, I only have an DEQ2496...
I don't think that move the DSP board is the right solution.
I would suggest:
- transfo replace the switched psu board
- psu goes at left of the dsp
but need more wiring and some ferrite beads around the cables.
or
- transfo and psu in a small external box with a multi-pins connector and cable (shorter as possible but in fact I don't know).
------------ | top of the box
psu
------------ | shield
transfo
------------ | botton of the box
What is the small board close to the tentlabs clock?

I've used this but max 15cm. You need to look for PCM 2.0 pcb connectors.

I again updated the BOM. Collected some digikey codes (but check for errors).

Hi Folk!
I've again updated the PSU schematics on the web site. I also added a "changelog".
More parts "tuning" are in the way to optimize performances or simplify parts sourcing.
I've some LT1963-3.3 TO220 in stock for the one who do not have access to Digikey or don't want to pay 30€ of shipping cost for one part.
