Yes, it will fry, to say the least!  That third winding usually provides about
2-3 volts for the maggie filament.  The transformer will not be able to
withstand the ~15 kV or so that theoretically you might get with that approach,
in fact the MOT will not withstand more than 4 kV even with careful precautions
and added insulation.  But you won't even get this far, because the fil.
winding simply can't take the current (tens of amps) you would be putting
through it even with no load at the secondary.

Hello list!
My MOT has three windings on it - one for 240v mains, one HV winding and also
one with about 10 turns which I assume to be low voltage, but extremely high
current - filament for magnetron?
If I plugged 240vac into this third winding, and drew HV out from either the
primary or HV secondary, do you think the MOT would fry?  If not, this would
presumably give a very high voltage and low current output, which is
considerably safer than the 2000V, ~1A output given in its usual
configuration.

Thanks in advance for any advice,
