The few turns of heavy wire is the filament voltage
for the magnetron. The single spade lug is the ~2kvac
output, and it is potentially (no pun intended)
lethal. The 2kvac goes thru a voltage doubler before
being applied to the cathode of the magnetron to make
it oscillate. Be aware that the 2kvac potential is
between the core and that single spade lug. You really
don't want to touch the MOT while it is energized.
It's a good idea to always use a 3 wire cord, and
connect the green(ground) wire to the MOT core before
you plug it in.

Cheers,

Greg
