[How to do instruction] Raspberry Pi power Supply

[rikardo1979]

For those who are on DIYAudio there will be a GB run by Tea-Bag for member Salas's new wonder, a nice linear supply. Stuff designed by Salas is "just" among the best, ever.
I don't see anything better for the Raspberry and such (adjustable voltage output, able to delivery high current on peak demand like a Raspberry does).
I plan to use it for my RPi & Allo DigiOne (less noise=less jitter and less noise injected in mains) and my TA2020 amp.

Thanks for share. Is this going to be something to ba available to buy as a ready made build, or just simple bag of components and PCB to do DIY with no case and no transformer?
