Pardon me while I take a moment to direct your attention to the website of KC5WA, who has been simultaneously working on builds of both my Tualatin and Willamette transceivers. RC does an excellent and really thorough job in documenting his work on his projects, and his web pages are a great resource for those who might be building or troubleshooting these rigs. Both pages are still a work in progress (as are the rigs), but RC updates them on a regular basis. Check out his very detailed page on the Tualatin or the one that he is currently working on about his Willamette build.
