Re: Tricked Out Microwave Oven

Hi, all the other messages have summed it up. the tube is running at its
limits now. the most common way of controlling power is varying the time on
verses time off. it is the wrong kind of microwave tube to be driven as a
modulator. the circuit is basically on or off and runs full power when on.
not much there to work on, the manufacture of them is driven by who can make
the cheapest one makes the most money.
