Default KEF Reference One Owners?

Hello!
I just picked up some Reference Ones that need some luv'n.

Can anyone help me develop a crossover schematic?
Here's what the crossovers look like. Can anyone print a PCB that replicates this?

The caps with 25 V and 50 V voltage ratings seem dangerously low, but maybe OK if they've survived so far. Use film and foil for the small 2 uf caps, Solen for the mid value caps . Higher voltage electrolytics for the 120 and 800 uf

if you're looking for quick, that board looks simple enough to buy a blank and use a dremmel to cut copper instead of messing with CAD, etching, etc.
