As a reply to my own question I can tell that Eprelectronics.com are able to supply E1 owners with a fuse cap holder which fit the EII and SP1200. The holder also seems to fit the E1 (as far as I can see without having the fuse).
Eprelectroncs.com can also supply the contact carriers (small see-through plastic wire under each key).
I still haven't found the specs for the european (220V) fuse yet. Although some members here have stated that it is a slow blow fuse but with different amp values. If you could fill me in on the specs I would much appreciate that
Best regards
