- 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.
