Not yet, but here is the drawings of transformers for new design:

I mean an IV PCB that can be used with the Buffalo-IIIsePro38, such as the PCB designed by Ian.
In fact, you only need to follow Ian's design to increase your transformer installation position. It can be applied to both Buffalo and Ian's DAC. You don't need to design two boards.

I recognise most of the components in the picture but not the board under the tower raspi + DAC + transformers
What is it?
I plan to design a PCB for buffalo DAC. Can you tell me the dimensions of the transformer and the position of 6 pins.
All the dimensions are actually can be taken from pdf I have posted previously. Here are the positions:
Pin #13= 0,0
Pin #1= -17.31,-10
Pin #2= -19.98,0
Pin #3= -17.31,10
Pin #4= -10, 17.31
Pin #5= 0,19.98
Pin #6= 10, 17.31
Pin #7= 17.31,10
Pin #8= 19.98,0
Pin #9= 17.31,-10
Pin #10= 10, -17.31
Pin #11= 0,-19.98
Pin #12= -10, -17.31
Is this a new version of the transformer? Originally only 6 pins
How is the transformer connected to the input and output?

I wonder what 6 pins are you talking about? Previously was the 9-pin version only and before that was the wires version. For now I am planning to making 13-pin version only, because I feel uncomfortable to manufacture two versions at the same time taking into account that 13-pin version is more durable\safer in terms of usage. I will provide connection schematics a bit later...
Here is the schematics for using all the 6 coils with ES9038PRO (stereo mode) or with AK4499 in Dual Mono mode.
The buffalo DAC has only three input pins for one channel. How can I connect the buffalo to a transformer with 8 input pins?
If there is no possibility to organize separate outputs mode, then the connection can be simplified to:

I Understand that the transformer's 3-8 pin does not need to be connected to buffola DAC.
For this circuit https://www.diyaudio.com/forums/attachment.php?attachmentid=795447
yes, pins 3-8 are NC
For me, this transformer is complicated, I can't design a PCB. I wait for you to provide the PCB for buffola.
@bisesik
Ivan does you trafo for DSC will also work with this new project ? 🙂
