        Just like in the good ol' days when tubes faded with age, so can
        the magnetron tube in your microwave.  It's a fairly common
        occurance.

        There are other possibilities (natch!); local brown-out from the
        loading of other appliances on the line. (I can hear the
        diffeernce when my toaster oven is on) or other circuit problems
        in the microwave.

        I'd bet on the magnetron. Unfortunately, magnetrons aren't
        cheap, nor are they a lot of fun to change.  Some TV shops (like
        mine) have access to lower-price magnetrons, but you might
        end-up spending $80-100 anyway.

        Of course, you could just switch to smaller meals. <g>
