i have made for some friends at least 5 DSC2 (me included) ... so i think the total number of the DSC2 around is 9 😀
After checking up on this, I got the main board from Vitopro, but I got the resistorboards from you.
These are the versions I am aware of:
DSC 2.5.2
DSC 2.6.2
An externally hosted image should be here but it was not working when we last tested it.

Hi it seems that inerstage transformers are the same for all versions? Except of last black color? Do You have the link where these interstage transformers can order pleae. And maybe some datas if You have inductance of coils, resistance of wire and other parameters IF available? Thanks 🙂
Hello everyone. I have a problem with my dac dsc 2.5.6
In practice I have the left channel that seems to play at a slightly higher volume than the right. To hear the voice in the center I have to move the speaker a little too much. I measured the AC voltage at the exit both right and left and it seems that the left sometimes has slightly higher voltage peaks. What can I check, what tests do I do? Thanks to everyone in advance.

Thank you for your quick answer. Can you kindly tell me where to measure with the tester on the resistors? do i have to play music ??
Do I have to check the DC voltage at the ends of every single resistance of the 64 ??

You need to measure the DC voltage at the output of the resistor matrix. This is the primary winding of the transformer. if there is a constant voltage, it means that some resistors are poorly soldered.
Measurements must be taken at the time of music playback.

Yes indeed, they are the same. I got mine here (you will find the parameters there):

I will have them measured really soon, will post the results. On top of that, I will receive also some custom made trafos (there is a thread here in diyaudio: Output transformers for DACs), and what is interesting there is that the core will be nano-crystaline. I will have them measured as well.
hi, I measured pins 10 and 2 of the connector that go to pins 1 and 2 of the transformer primary. On the left channel the direct current is about 265.5 mV which practically stabilizes, while on the right or nearly 1mV it is also 0.
What to do?, I'm in love with the sound of DSC 2.5.6 please help me, create dependency ...
thanks ppy.
Hi guys , quick question : If I am using the dac in rca output mode do I short the unused phase of the balanced output to ground?

Hi if possible you can tell me what to do and how to solve, you are the only one being the product manufacturer.
The card that was sold to me among other things comes from you ...
Thanks again.

Thanks Nautibuoy.
I had written a few posts back on my problem, obviously if anyone knows how to solve it, so be it.
Also if someone has made DSC 2 with "reclocker ppy" or has some other DSC card I am willing to buy it.
Thanks

The presence of a constant voltage is a defect during soldering or microcracks. Try to carefully view the failed channel through a magnifier or microscope.
If you have an oscilloscope, then the problem can be found very simply - sequentially view the signal on each resistor.
P.S. If the board was sold by me, then I am ready to take it for repair.
Wondering for guys who hand assembled the DSC2 cards, did you use a solder iron, solder paste and a hot air gun, solder paste and a controlled oven, or some other means?
I don't have a hot air gun. I'm trying to get the parts for an oven, but that may take a while. Could use this as an excuse to get a hot air gun lol.
I was looking at the pwb, and while I'm pretty sure I can hand solder, not sure if I want to spend that much time soldering.
Seems like using solder paste will be faster, but never tried it.
