i highly doubt any microwaves at all would be generated once the 
magnets are removed, and i dont think there would be much residule 
magnetism as the anode cylinder is made of copper...

Hi,

When microwaves hit a metal surface, they bounce off and in the
process, induce a voltage in that metal. An example of this is when
you put a small strip of aluminum foil in the microwave, it will blow
like an overloaded fuse as a result of the induced voltage. Using
that knowledge, a thicker piece (so it will not short out) of the
aluminum foil, can be placed in front of the magnetrons output to be
monitored for any voltage fluctuation across the aluminum that would
be caused from microwaves hitting it. Im not shure on how much
voltage or amperage this will induce in the aluminum foil but I hope
this helps.

Hi, i am interested in this project. leave the heat sink fins and the two
inductors on the filiament leads can be left there, no problem. it probably
will require air cooling with just the filiament running. a computer fan
should be plenty. read the power input with the filiament on and then with
power going thru it as a diode. if the tube is making any microwave output
it should draw more current. worth taking note. not sure it is a perfect way
to measure for microwave output. cul brian f.
