In isolation (assuming all power supplies could handle the 220 volt, 50 Hz input), your Amiga would work fine. That's a big assumption, though! Be sure to check the specs. Essentially all of Europe is 220 volts. Certainly (unless you have "international" versions of the equipment), you will need a stepdown transformer. (That's the easy part.) The real question is, "Will the various pieces work on 50 Hz?" For the answer, you will have to check the nameplates on each piece. If they all say, "50/60 Hz" or some such, you're in luck! On the other hand, if one or more nameplates read "110 V / 60 Hz", you have a problem. . . The reason equipment sold in North America may not work on 50 Hz power is that larger, heavier, and more expensive transformers and capacitors are required in the power supply section. It can be dangerous to run 60 Hz equipment on 50 Hz, as transformers may overheat and catch fire. If the power supplies will cope with 50 Hz, then your Amiga will work well in isolation. The Amiga generates video that conforms to NTSC timing, regardless of powerline frequency (after all, internal power is DC!). The KV-1311CR will continue to accept video that conforms to NTSC timing, regardless of the powerline frequency (again assuming that it won't catch fire on 50 Hz!). Of course, you can't tape the output on a PAL VCR (take your NTSC VCR with you, _if_ it will run on 50 Hz. . .). Enjoy your year in Europe. I hope your Amiga can make the trip with you!
