If you are using a shunted xfmr such as an NST or MOT, then a
charging reactor is not required.  The reactor is used to limit
and define the charging current in a 'hard' DC supply, whereas
the MOT's mag shunt will define the max current in your system.

I don't know if the BIL rating is sufficient on MOT's to put
them in series; will they operate with one output term at gnd?
