There was a Schematic bu Thierry (surname???) I may have a copy - will have a look. Don't think there were any restrictions in circulating them. I'm sure someone can advise if there are. Will have a rummage.
IRO knobs, there was a post a few weeks ago about them but I didn't look at that one. Also, there was a Scandinavian(?) company who do them I recall. Just found the post from 14th May 2010. Company is called Elma but have a large minimum order Ed Rose on this forum bought a stack - he may have some left.
