Hmm i see you all fell in lowe with this 16 kV neon.

Well if sombody would pay the shipping i could call my friend that owns a
company that makes those "super strong NST-s" and ask him about a price?
They could be epoxy potted ( cannot be disasembled) or  HV polyurethane
potted so shunts, windings can easily be remowed and so.

He can make any transformer at any current and at any voltage and at any
setup ( CT, non CT) or whatewer.

I guess he would ask for this neon somwhere arround 400 $ or somthing like
that.

I can ask if  you want
