I am going to build ESP's P101 amplifier (150W into 8 Ohms, 400VA trafo) but I do not want to mess with creating my own PCB for the power supply. I found couple on Ebay that look decent but I would like to get your opinion if they are suitable for this amplifier.
board 1
board 2
Also, sellers do not provide schematic or BOM. How do I know what component values (be sides the main caps and rectifier) should I use? The blue board looks like it has only two additional capacitors but the other board has a lot more components. For the main caps I was planning on using 4x4700uF as recommended on ESP's website. Rectifier is going to be 400V 35A.

Hi,
remember , that board 1 allows only 30mm diameter capacitors, usually the common sizee is 35 mm. I used these boards
Capacitor Filter Bare PCB Support 6pcs D35MM Electrolytic Capacitors | eBay
and mount my rectifier bridge on the heatsink. This board allows you to use 4 or 6 capacitors and allows different footprints and different diameters.

Why not use the one in the Diyaudio store?
