For a concise listing of voltages, frequencies, and connectors, look in the Panel Components Corp. Export Designer's Reference, available from: Panel Components Corp. po Box 6626 Santa Rosa, CA 95406-0626 1-800-662-2290 1-707-523-0600 Just a quick look shows 16 different connectors (8 in Europe alone), 10 different voltages and two frequencies, both 50 and 60 in Japan. I have found the reference to be very helpful in preparing equipment for use abroad, and I wonder how I got along without it. Happy Trails, Galen Watts
