Hey Mike,
The only magnet I could find in the manual is part # E-184-284
It seems to be a fairly unique magnet assembly for Centaur which is a bit of a problem..
A quick search on RGP failed to locate any of the usual suspects..
My first suggestion is to try PBR (
http://www.pbresource.com).
IF that fails try Marco Spec or Bay Area but I wouldn't be too confident.
If all else fails, PM me as I have a contact going overseas soon who may have access to some parts...
