B. The price will be as followed:
On set (4PCB)
1. PCB- DAC END =$15
2. PCB- Salas Shunt For DAC=$15
3. PCB- I/V stage =$15
4. PCB- 10M45 for I/V= $10
5. Worldwide shipping: $ 5
6. paypal fee: 3,5%

Total: $62.5

You can set 2 pCb: PCb DAC-END and Salas shunt For DAC-END. Total = 36.5

Thanks for fast response...
I think It doesn't take a long time saving for those price

======================
How much do you spent for all components (means : Chip DAC, Resistor, Caps, Jfet, Transistor etc... for a complete DAC?)

What gift to Salas? Thanks, but please take that out. I said many times in my threads, alright, you people can make whatever I publish, or make a GB for DIY use ONLY. Have fun.

Have you actually built up one yet? To make sure that the design is indeed functional and works properly?
I would hate to have built one up later to discover that some of the traces on the PCB's were laid out wrong.

I ask because I tried to make my own 1 off PCB on this design and triple checked the scheamtic against the board I made. It was 100% correct, but yet it did not work at all.

While I appreciate the effort of making these boards available for people here, I must say I do have an issue of someone using the names of Andrea Ciuffoli and Salas, apparently without permission and arguably for profit making purposes. I think the original "inventors" of the circuits deserves a bit more respect than what is shown here.

Just a personal opinion of a member; nothing more.

Regards,
Patrick

I was wondering who was going to say something. I mean, Salas gets like, what, 4% of the profit? He worked hours and hours to develop this circuit and helped so many people to get it right, from his own time. Then somebody comes and makes a healthy profit, and Salas gets 3-4%? Me thinks it's unfair to him to do this.

Salas, if you don't agree with him selling this for profit, then you should take it up with the site admins. If you're OK with it, then I retract my comments.
