New linear ultra low noise power supply prototype - yannig - 07-28-2019
I just finished a new dual regulated power supply for a Raspberry PI3B+ / Allo Boss combo.
the (very woody) server and his (woody) dedicated power supply.

ultra low noise series regulated power supply with LCL filtering and dual coupled bobbins choke for the Raspberry
ultra low noise shunt regulated power supply, with LCLC filtering and dual coupled bobbins chokes for the DAC.
I use MAT0x for differential amplification
And I'm very very happy with the listening ! : much better silence, and much more colors, resolution and softness...

Quite unusual aesthetics (in a good way IMHO)...
Are the black boxes housing the transformer and the bobbins made of metal?

Thank you very much for your quote !
And yes, black boxes are oven-painted steel cases from my usual winder.
