Abstract
In a microwave oven system comprising at least one magnetron of a given operating frequency and a mains unit for the at least one magnetron, the at least one magnetron of a given operating frequency is replaceable by a magnetron of another operating frequency. The magnetrons of the different operating frequencies have at least approximately the same mechanical dimensions so that they can be easily replaced quickly. The mains unit can be used for the different magnetrons in unchanged form or in a form involving minor modifications, without any change in the electrical parameters or with a slight change therein, thereby affording interchangeability of the various magnetrons.
