Good point Ray. Dont know. Seeing as half this stuff we play with comes in it hopefully not an issue!
So powered up for a few hours. Ubib stone cold so I think it needs some extra spare CCS!
Reputable suppliers don't supply sensitive componemts wrapped in ordinary bubble wrap Jim. You can get anti-static bubble wrap if required and I reuse the 'silver' anti-static that I get parts in from the likes of mouser and digikey. Finallly, when handling ESD sensitive parts I use an anti-static wrist band.
You're quite right Ray, I shall amend my ways! I seem to like living dangerously in more than one way too, I woke up and straight away asked myself why I was feeding it 20v. I'll lower that to 15 or 16. Must be the trafo 8932 thread that was in my head! Hope I didn't damage anything.!
Hello abraxalito, I have done the Step 1, all TP voltages were nominal(+-0.1v), after soldering Step 2 components I've got 11.9v at TP6 and 1.9v at TP8.
Any idea what could be the problem? Thank you in advance.

Hi Yuri - TP6 being much too high suggests a soldering problem on U16. If it looks all fine visually then measure the voltages on U16 pin2,3, 6 and 7 and post them.
Hi abraxalito, you were right, as always - I have resoldered and now voltage is as it should be. Next problem to solve would be how to connect the input board and it's power regulator. I will post the pictures tomorrow.
Thank you!
Thank you!
Playing sweet sweet music!
Salas Ubib at just under 15v feeding the dac. LT1963 at 3v8 feeding the 3v3 LT3042 powered WM8804 receiver.
Signal is optical from a Google chromecast audio.....my go to streaming device.
Sounding very nice indeed. I'm not good at subjective 'reviews' but this sounds as good as anything else I've built which is a fairly tricked Ian Canada dac with Andrea mori clocks and multiple psus, and also a Miro AD1862 dac with TPS7A4700 type regs and a AK4118 receiver.
Like I say I don't seem to have the memory or vocabulary to compare different sound quality elements from the different systems, but this sounds as good as you 'need' to and for a very wallet friendly outlay.
Thanks again Richard and to your wife.
For completion it is playing into a Salas DCG3 preamp amp, Dibya Xmas TDA7293 power, and B&W DM14 speakers.
A quick edit....I do get some healthy pops when changing from say Radio Paradise to Spotify, or if Spotify has stopped playing music it'll pop when starting again. I dont know if this is the dac or receiver?!

Great result Jim, thanks for sharing the pic.
Trafo looks very weighty, how many VA is it?
Clearly the pops are made by the DAC but perhaps there is a sample rate change going on which makes the Toslink receiver blip for a moment? I don't have a Chromecast but I have found Audacity can make a pop when restarting (un-pausing) in Windows. Foobar does a gentle fade so is preferable.

Yes its maybe 100 to 150va going on size and weight. Made by/for an audio company here in the UK. Quite nice...shielded/ goss band whatever that is!
I have a DIR9001 board to try. I've never had any sound out of it but I'll give it a whirl today.

Hi Darksound.
This is how you connect the boards
SPDIF board // DAC board
GND // GND
VDD // -
BCLK // BCK
DATA // DATA
LRLK // LRCK
MCLK // -

You might find you don't need the gnd wire for i2s. I noticed my ground wire was off last night but it was still playing music!
It may play music.
In such a case it is good practice to test the DAC output for noise both in idle as well as while reproducing a test tone.
You may use REW free software for that https://www.roomeqwizard.com/

Busy old day today and to be fair its done my swede in a bit! Trying to fathom it all out and keep it neat. Still a long way yet but getting there.
Got the Fifo u.fl rigged up to the dac. This rig was all 'Ian Canada ' but I've taken his ess dual mono dac out and I'm using the digital front end to feed the Phideca. Powered by various Salas shunts and Ian batteries. Along with Andrea Mori entry level 22mhz clock.
Hope to hear it all soon!

Hi abraxalito, I need your help again for troubleshooting. I connected the filter and the SPDIF board, but no sound. Tp8 without filter is 3.77v, with the filter 3.84v,
Tp7 filter is 3.77v, with the filter 12.47v. I will try another source tomorrow, instead of my computer, but first I want to have a correct voltages.
Thank you in advance.
