I believe its this page: http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_6582_base_pcb_construction_guide&s[]=revision&s[]=1
It mentions that rev 1 pcb bought directly from Wilba are missing tracks. The links on the bottom are from the old forum software. So they don't work anymore.
It seems older posts are still available. But you can only manually browse them, the search option won't find them. I can't seem to find the specific ones mentioned on the above wiki page though.
