Hi Team

A point that assists in insulation:
In a 4 MOT stack the inner part of the outer MOT secondary only needs to
hold off the potential of the first MOT feeding that point. ie about 2.2kV
The potential rises in the secondary as the winding extends away from the
core.
Thus even in a 6MOT stack the last MOT secondary is only holding off 4.4kV
where the secondary meets the core.
