ES9023 / WM8804 S/PDIF DAC Group Buy - Page 16

syklab · 06:25 AM

I am also interested in the PS PCB too, spreadsheet updated, but can it be handled as a separate small GB? I can't wait to get my hand on the DAC.

Thanks

I'm not super clear on this. Will the extra waiting time be only for people who are buying PS boards? If we don't want a PS board, should we put "0" or "no" in that column, so our boards and chips can get shipped out as soon as they arrive?

Subbu is doing the group buy so we should ask him. My guess it would be simpler to send out the DAC PCBs when they come in and do the PSU PCB after that. Please keep it relaxed, we put much time in this (not only for our own pleasure).

Subbu, can you tell what the plans are concerning the possible second group buy of PSU PCBs ?

OK. I'm relaxed. I have my feet up on my desk and I'm sipping my coffee.

can a single power supply handle 2 boards in balanced mode? or will we need 2?

The plan is to send the PCBs and DAC for all the members as soon as the PCB arrives. Members interested in the power supply PCB can choose to wait and get them all together otherwise there will be an extra shipping cost to it. So if you are not interested in the power supply then there is no extra waiting time.

We will try to post the details of the power supply PCB over the weekend. Please keep in mind the PCB manufacturing takes about 10 business days and 2 - 3 days for me to get them. Please update your preference in the spreadsheet.

Hope this clears out any confusion.

Thanks!
Subbu

I have been running the balanced version with single power supply built using an LM723 and pass transistor. Since we are also looking into a discrete regulator we will update the thread with details soon.

Hi Subbu,

Thanks so much for all your time and effort put in developing this for the DIY community, there is a lot of work in managing the GB, highly appreciated.

Thanks
