I'm never going to find a use for all of my NSTs, so I'm liquidating.

All of the ones currently up for sale are center-tapped non-SGFI 30mA NSTs. They do not saturate when driven at 140V, so they are also variac friendly. I've got 9kV ones, 7.5kV ones, 6kV ones, 5kV ones and 4kV ones.


$35 each.


Shipping to anywhere in the USA is only $12, and 2 can fit in a box.

Just curious Grenerino -- are you sure those all have center tapped secondaries?
In my experience, this form factor (with inverted HV bushings) is used in things like pedestrian WALK lights.
And the lower voltages (e.g. 4 kV) have one end grounded.

No 15kV ones :-/

A 9kV one fed 140V will put out 10.4kV though, which is 14kV when rectified.
