I can sell all resistors for this DAC!
Would you care to post a price on all resistors? I can move on to other parts.
Strosek,
Would you mind sharing your BOM with links to suggested components (if it's not too much trouble)?

Quanghao, the circuit for SSHV posted above lists for D5 & D6 - 1N4142A but the BOM (on page 179 of the original thread) says 1n4172?
I suspect the part we want here is 1N4742 or 1N4742A a 1W 12V Zener Diode....
Is this correct and if it is could you please make the corrections to the circuit so others don't have a problem.
Thanks!
Strosek,

If I had one I'd be happy to share It but all I did was use Quanghao's BOM and I just held off on ordering parts that I wasn't sure about ie. the diodes I just posted about.
I sourced most of the parts from Mouser, Digikey and just a few things off ebay.
I'm 95% done... I held off on the diodes and power supplies which I'm hoping to get from Bud P if he ever responds to my PM's.
If you need specific assistance with a certain parts please PM directly and I'll see what I can do as I do have many extras.
Thanks!

One quick question, in the BOM, there are 1/4W, 2W right next to resistors. I assume these mean power rating of resistors. The spec of CCF50 says it's 0.33W so it can handle 1/4W OK but how about "2W" on the 33 ohm resistor?

Yes! 33R use
VISHAY / DALE RN65D SERIE : 75R// 49R

Resistor 1/2W 3.3 Ohm x 1 R7
47 Ohm x 2 R9,R10

6.8K Ohm x 1 R14
On PCB R13 6K8! = 6.8K
R14 200-220Ohm! = 200 or 220R
which version is correct? (scheme corresponds PCB)
Thank you!
No correct!
Thanks
No correct!

Please explain.... Which is correct? I don't understand?

HI!
in the PCB print 1n4142, it is wrong!
this i ok 1n4742 , zenner diode 12V
Hi !
I got to the final! But something strange happens to 6.3V power supply!
AC voltage is 12-14V/ 3A! After about 15 seconds the relay flashing and DC voltage increases and decreases between 2,5V - 6,3V! I use R 80-36 R core transformer from DIYCLUB! Which may be the problem?
Thank you!

you can mesuare after diode, befor LT1084!
How many is it voltage??

12-14V AC, it´s not a little bit to high? All the scheme says 6,3 -9V.

for heating you got all the 3,15-0-3,15 and 2,5-0-2,5 in serie?
Put only 3,15-0-3,15 and 2,5-0 in serie,
or 2,5-0-2,5 and 3,15-0 in serie.

Sorry, wrong quote, it´s for Hotzman and the configuration of the heating on his 80-36 R core.
