You mean pro board,emulator+SPDIF all in one?If so,please atached this picture,list of elements,program for PIC and pictures,so i can normaly make this all in one pcb and starts liostening to mp3s in my HU tuner list.

This is amazing, thousand thanks!
Can we have a higher resolution of the first image (the design) ?
And can you tell me what size the pcb is supposed to have so I can print it correctly ? We're doing 4 here !
Thanks a bundle!

So here is the schematics.
Protel sais that the board is 78.73951mm X 82.012mm
But remember, if you print the board try at least 1 ic on it if it fits the size ( befor you iron and etch the board ).
And let me know how you succseeded.
And the 74ls04 supposted to be 74hc04. Sorry

Why is there so many connectors on each side?14 on left and more on right?
Is this PCB double sided,becouse of picture?(UP has a line or to to bypass?)
Is the second and third picture swaped betwen,couse TOP looks to me like bottom where is no elements,and BOTTOM looks like UP where the elements must be.

Ok I started looking online for the components, and I cannot find the Schott 22083. Do you know where to find it or what can replace it ?
I have a friend that can print the circuit board for me, but he would like to have the design file in its original format so that if he doesn't have exactly the right components he can adapt the board, would it be possible for you to send this file ?
Thanks a lot!
PS: The components I have found so far seem to add up to about 65€, is it close to what you found or do I need to find a better supplier ?

You can replace the transformer with PE-65612. Visit cirrus logics home page and look for the "Recommanded SPDIF transformers" data sheet. I'm not sure that this is the exact name but you can find in under products/cs8406.
The price for me was ~17 euro ( excluding the board ). You deffenetly have to look somewhere else.
The board was designed in protel 99se. The files are 17 Mbytes, so it is far too big to send by mail.
Your friend can design it from the schematics and can modify the footprints as desired.

do you know if this emulator can work on before-2000(non tuner list or update list) models??
The communication with the cd-changer should be the same, because the cd changer is the same too (a Philips RC026 renamed CDC026 after year 2000).
My HU supports D2B communication and here are some pictures
The only difference between the HUs is that mine accepts analog left and right channels so... I think I don't even need the spdif converter .. am I right?
Do you have the schematics for the emulator only? How much $ do you think it should be?
Thanks in advance,
