Exclamation +/- Power Supply Professional PCB

Hi to all,

because i need a individual +/- Power Supply for my next projects, i have made a new PCB.
Here you could insert up to 15 caps per rail. All caps are parallel so the ESR of each cap would be lowered.

I would make a new group buy for those, who would like to have a perfect solution.
So the pre-orders could start now.


Click the image to open in full size.

The rails are strictly separated, including the ground lines!
If you like, you could insert a decoupling cap and a bleeder resistor.
I choose a copper weight of 105 m, so higher current applications are no problem.



The PCB has the following data:

Material: FR4 - 2mm
Layers: 2
Board size: 195x120 mm
Surface finish: Immersion Gold
Copper weight: 105m
Soldermask: Both sides - green
Silkscreen: Legend on top


The price will be as followed:

Professional 2-Layer PCB: $23
Worldwide shipping: $ 9
Europe shipping: $ 5
paypal fee: 3,9%

A donation of $3 USD to diyAudio will be done for every pcb sold.


Pre-Orders only at: diyaudiopcb (at) gmx.com

Best regards to the community,

this could easily have been made a single layer, does that not keep manufacture costs down?

I have ordered this PCB (2x) as part of the TDA1541 package. Just out of curiosity, why the HUGE capacitor banks on this?

When used with 1000uF caps, the total capacity is 30.000uF (15k per bank). When used with, say 3000uF, it of course increases dramatically to 45.000 per bank. Seems quite a lot to me for a DAC, no?

And why not a smaller bank with more (larger capacity) caps, like 5x3000?

Just curious about the sonic effects of this setup....
