Please have a look at Fedde's site. His Nonoz II was made on one of my early version pcb's. Imagine that one with a discrete power supply for the TDA and Super E all the way.
Yes, I would like to have such a PCB. 
I am about to order some parts myself and try to make my first
non OS dac. (actually my first dac ever
)

Adjustable for the ones that run the TDA on 230 V 😉
Seriously: it will be adjustable to 7 or 8 V or so.

Hi Jean Paul,
I will take it that the PCB will include the bridge and preregulator up to unbalanced RCA analog output with passive IV.
May i suggest to include header for the I2S Input to the DAC so that one can feed the I2s signal externally using reclocking or direct from an old cdplayer.
Keep me in the loop as i am interested in it.

I could have missed it in previous posts 🙄 , but are there any estimates on how much $ the PCB gonna run for each of us?
Also anyone knows good place to get the chips in Canada, Toronto?
Thanks
Alex

Here is the address of Rob's page:

(Projects->A minimalistic DAC)
BTW: the dutch language page has more information about the NonoDAC...
Have fun!

it'd be great to organize a single parcel to canada (to avoid multiple shipping costs and import taxes) and then distribute them within

I too am interested in joining in. I have for a long time been thinking about building a simple non-oversampling TDA1543-based DAC, and this seems like an ideal opportunity. Jean-Paul, do you have a guesstimate on when the boards will materialize? Any guess on price? Might it be economically wise to do a group order on chips as well? I guess administration is easier since we're getting the boards as a group as well.
Konnichiwa,
May I put in some suggestions/requests for this Board?
First, provision the use of both receiver and Chip as DIP and SMD encased Item, as supply becomes more problematic.
Second, consider providing for the asyncronous reclocking (SMD Chip 74AC74) using a canned X-Tal Oscillator.
Third, how about allowing for the use of both TDA1543 & TDA1545, including the required different components on the "ref" pin?

I would be interested as well if it had a provision for I2s input and possibly supported TDA1541A

Is the CS8412/TDA1543 combo phase inverting? I think I read that somewhere, but I would like it confirmed. If yes, is it possible to get the correct phase in other ways than reversing the speaker leads (eg. reversing pin 9 and 10 on the receiver input)?
