Per Larrys comment, to the best of my knowledge the most current W7IUV
design is captured in his Revision 5 document, and the schematic within
this document that's the most current design is identified as follows:
Revised 13Sep09.
Here is a link to Revision 5 document:

I built my W7IUV preamps per the "Revised 13Sep09" schematic which I'm
pretty sure is the most current design.
