Is it dead(how to make sure) or perhaps requires say 1v higher cathode
heating voltage than what transformer supplies?

Watch out for a big capacitor in there which in some cases can give you
a nasty high voltage bite even after the oven has been unplugged for a
while.

Or as a guy I know would so eloquently warn... "Dont ya'll be messin
with that s**t lest you know what you doin; it'll up'n give yo ass a
dirt nap"

Good advise too. I hate 'dirt naps' anymore, especially now that I'm a
bit older.

Microwaves reached disposable appliance status eons ago... if it's not
in warranty, spring for a new one, they're cheap.

I meant what is going to happen if you try replace original magnetron
with one that has 4.13v or 3.6v filament voltage but original hv
transformer gives 3.15V
