My understanding was the parts will be part of this GB. It was changed or it was my misunderstanding ?

With that many people it is good idea, but it can be challenging logistics task

Well done and many thanks to Subbu and Jean-Paul.
A parts GB would be good, perhaps organised regionally as seemed to be developing ni the original thread.
Many owners clubs, particularly for cars, have discount deals with suppliers.
Does anyone know if Mouser, Farnell or Digi-Key (or any other supplier) ever offered a "package" for a group buy. Whilst it may not be as cheap as a genuine group buy, it could solve the logistics problems.

I hope such a thing exists, it would indeed solve a lot of logistic hassle.

BTW the PSU can be used to 1 A (but not with the onboard transformer, you'll need a 1 A or more off board transformer for that). It is now possible to use it for a Squeezebox etc. Please understand that the transistor must have a heatsink then. You can bend the pins and put it in the PCB from the under side and mount it on the chassis with an isolation pad and ring. Tighten the screw and bolt and then solder it. It is better to include an aluminium L profile between the chassis and the transistor. This will depend on your needs and you'll have to try out yourself as we made this PSU for our DACs. The DACs don't need much current and a heatsink is not required for feeding the DACs but adding a small vertical aluminium L or U profile won't harm.

Hi

Similar to the previous GB, the parts were organized as a independent GB by Phil (korben69). The scope of this GB is limited to the PCB and ES9023 DAC. The reason to include ES9023 is that all other components can be purchased from Mouser/Digikey/Farnell. The BOM will include part numbers from all these three vendors.

I am sure Phil will chime in here soon with more information.

Hope this helps!

Is the BOM transformer the same as for the previous version of the ps board?

Thank you for the hard work of organizing this group buy.

In the Subbu DAC V3 order form, there is an option:

Would you be interested in I2S version?

Does it mean that there will be another PCB for the I2S version?

Or, is it simply the SPDIF version without the WM8804 chip?

Subbu,
I assume this group buy is for the single ended version. Is there still a plan to release a balanced version? As far as group buy for parts there is no significant gain (savings or availability) so I see no need. That being said if I can be of any assistance with distribution of this group buy feel free to ask.

Bill

Yes, if you use it for a Subbu DAC.

No it is another version so for SPDIF you need this one. One chance and last chance.
