I was going on information from 40 years ago. Items back then might not have been converted easily (60 to 50) cycles. I remember rather large copper colored boxes (16" by 8" by 6" or larger) boxes that heated up excessively for use with appliances brought over from the US to Germany. Maybe computer makers have figured out the technical issues to make the boxes obsolete by now. Ed
