Smeggy,
If you look at amb's site you can still find the BOM that I did in an excel spreadsheet. If you can manage a paint by numbers type of exercise (really, it's just a matter of taking your time) then you should be able to stuff the pcb just fine. Same deal with the power supply. And I for one don't see much need to deviate from the standard parts list for 99% of the build. The only changes to the PS would be to upspec the trafo and heatsinks and same with the amp, just beef up the heat sinks.
I might even have some parts to donate to the cause.
