My new project LKS DAC

[Light Dependant Resistor]

That's quite an impressive project Yetkin. Seems a hassle but how about using solder to join the shielding?

Nice layout ! reminds me of some of the best Pioneer CD players

Yes a good suggestion, maybe remove components temporarily when using what would be a fairly hot iron.
Slightly higher priority if it was me, would be to use coax shielding as part of the wiring. To do coax shielding, the method I use
is to extract the inner core of say RG58 using the silver wire vs copper outer shield type, then use enamel wire for the required wire from one point to another.
You are then in effect, if the coax shield is connected to the copper plates at ends, extending the benefit of the shielding throughout.

Using a Star earth as well his DAC project will ensure best grounding practice. Remember to connect star earth to chassis
and wire to safety ground.

Thanks for recommendations.
Thought a lot on how to make the connections of shielding. In home condition making the soldering will be challenge for me.

I did not tried but do you thing soldering machine 400-450 C will be enough. I am again away home but tomorrow evening will be back to Istanbul.

I will be carefull with safety earth Chris

Back panel and top covers are cut. İnputs and outputs at back panel are opened.
And at last for now, a raspberry pi2 have been embedded inside chassis, which will be powered with the remaining 5v LPS line.

It's rather large! Could you put some of the circuit boards on their sides?

Yes it become big. I worked several layouts, at the end decided with this one.

why I choose this.
- the shortest possible AC and DC lines inside the box
- having reserve place for future upgrades
1) clock module with separate lps
2) ı2s module for raspberry (Ians Fifo or similar)

Here there are the AC and DC lines and connection points at pcb.

Finally I could find some time for the project and wanted to finish this weekend. Unfortunately Murphy's Law was there. I could not get voltage with transformer at the secondaries of 230v to 15 v's which was for bipolar. Contacted supplier but will take some time. So I order a new one from local producer.

So far everything is ok. 5V s are working. Raspberry active. Screen is working.
Made again gomme-laque french polishing with matte surface but still the texture of mahogany visual.

Finally I have completed my new DAC

Last 2 days I am listening. Very promissing. After burn -in period all will settle.

I had a problem with bipolar Placid HD power supply, surprisingly we understood that the problem was with PCB after bridging externaly a resistor and cap it is solved.

Now all works fine.

Next stage is setting up raspberry pi with picore player and separate vortexbox server.

Another lovely job Yetkin.. Love the wood you select.

Thank you very much Grant. I made one more frame of this wood and going to change valve pre chassis.
And also add a front panel from this mahogany again to power amp.

Rack will more look like in order.
