I'm new to pedal building so please be kind

I've been looking on the net for about 3 weeks now for an accurate PCB layout that I can use for etching and schematic to the original version 2 18v power boost. Nearly every search lead me to a 9v Overdriver layout or schematic. I know the differences in the circuit are minimal, but the end result is like night and day. The power boost for the uninitiated has a much larger amount of headroom before the gain kicks in, therefore the boost in volume is cleaner, where the Overdriver breaks up earlier and acts more like a common or garden overdrive pedal.
Anyhoo, I digress..... There's plenty of pictures on the net of the actual circuit board components, here's a picture of the new reissue from the Marcaris web site

And here's an image of an original power boost board

What I'm looking for is a printable PCB layout, and the correct period circuit diagram for an 18v power boost. The best diagram I've found so far on the net is this one, the later version is the one i'm interested inas that was probably the one that Gilmour used

Has anybody ever built this version..... And what are the pit falls if any are there with the build.
