In a recent discussion, a friend mentioned that the klystrons in microwave
ovens can degrade (somehow) over time, putting out less power. I went and
measured the output of our oven (I'd suspected it's been low for some time)
and found we were getting about 250 - 300 watts out, for an oven rated to
draw (under) 900 watts from the line.

Do klystrons in fact degrade? Is there anything else could cause this?
