I told you the 4148s would be the most painful part! But they do actually provide a "bridging" function that you don't get with SMT parts. You've got it right: RN17 is on the top side, bottom right corner. RN18 is to the left of RN17, top side, just before the button pads start. Schematics available here: http://www.ucapps.de/mbhp/mbhp_blm_scalar.pdf http://www.ucapps.de/mbhp/mbhp_blm_map.pdf I don't intend to publish the layout files; seeing as there are very few users I'm happy to help on a case-by-case basis.
