circuit board layout from a schematic

[Bushbaby]

I have decided to go with the following design which is an upgraded form of the Marshall 1930 design created by Bo Hansen (see attachments). I am lucky to have a small stock of ECL86 valves, both used and NOS. Its also made me think of a future project using PCL86 as I have a stock of NOS valves too. 
I've had a custom made cabinet built for my initial project. I am just concerned that I might start on this project and c*ck it up!
