i have one question on the PCB , what is the purpose of the two 15000/22000 Capacitor in parallel with the regulator output ? i don't see them in the original schematic , is it for the VFET load or just to do a CRC filter for the Buffer?

These are the "buffer" caps of the VFETs' powersupplies. They grant a sudden powerfull ease IMO. They are not mandatory and you may leave them. I like their tonal signature yet.

BTW, I have paid the boards meanwhile and expect them to arrive here soon. I ordered ten more, eight of them are still available.
