- If the system is built to Terrys specs - and mine is - resonant
rise is a precondition for correct operation.

- IMO resonant rise is not a special issue for MOTs but for other
trannies as well. Unfortunately I can't select the inductance of the
secondary winding of the MOT. I have to accept it as it is. Have you
calculated the resonant frequency of your pig/primary cap combination
already?

- As usual: No specs, as it was salvaged from dump. Unfortunately I
had not measured its secondary inductance before.

- I would like to avoid resonant rise in order to protect the MOT but
at this moment I do not know how it could be done.
