Re: Low-voltage NST

Is the NST is in a casing with tar or bare? If it's bare; is the
secondary is form by one coil or two? I presume you test with an
ohmmeter if a connection exist between the hv coil and the core.
Any way if the nst have only one hv coil it probably could be
ground. I have a small nst like that and the hv coil is ground to
