There are approximately five manufactures of microwave oven magnetrons in the world, and these manufacutures are located in the Far East. Anyone manufacturing a microwave oven must purchase the magnetron from one of these manufactures.

What this means is that many manufactures use the same or similar magnetrons and that many are interchangeable. Many years have been spent developing the most comprehensive cross reference in the industry. If you would like a copy of this cross reference.
