In a previous article I wrote: > Mac will work with 50Hz 220V power withOUT a > transformer. At least a Mac plus will. That was WRONG. As Werner Uhrig <werner@rascal.ics.utexas.edu> pointed out in a private mail, directly use 220 power on a Mac+ will damage it. Sorry for the inaccurate information. Hope it did not do any damage. I have already cancelled the original article. But nevertheless, you don't need a special transformer, Mac+ will work under 50Hz and 60Hz power. So you don't have to have a special transformer, a usual one will do it. (I checked the Mac+ owner's manual this time.) And If you have a SE/30, it will run on 220V 50Hz.(It is written in the SE/30 owner's manual and on the back of the SE/30). ======================================================================= USMAIL: Guangliang He | INTERNET: ghe@PHYSICS.ORST.EDU Department of Physics | BITNET: hegl@ORSTVM.BITNET Weniger Hall 301 | Oregon State University | Corvallis, OR 97331-6507 | PHONE: (503) 737-4631 =======================================================================

You do need a "special" transformer, in the sense that a 50Hz transformer is not the "usual" one you can pick up in the US; it's typically a special-order item. A 50Hhz transformer is the normal one in Europe. A 60Hz transformer could melt down when operated at capacity with a 50Hhz supply.
