Dave Hunters book has helped a great deal. I also recommend How To Service Your Own Tube Amp by Tom Mitchell.
Building pedals has been helpful, especially the mod kit style pedals that are more of a point to point wiring scheme. Neatness and placement are learned with the tight quarters.
I am glad this site is available as the Two Stroke has been one of my favorite projects to date. I am thankful for all the help from Andy and everyone that has posted info and tips here. This place and the people here are a valuable resource.
