AAAAAARrrghhhh!

DONT plug it into the mains!!!!!! It may explode and it will certainly pop
your breakers!!!! This sounds so dangerous even I wouldn't try it!!! These are
induction coils, not transformers.

The HV out is the fat center terminal. The other terminal is the case
(ground). The remaining terminal is for the primary (the one you *don't* want
to connect to the mains!!)

You can drive this from a power-oscillator or a cap discharge circuit, rectify
the output (with a really HV rectifier) and use it to drive a DC, slow-shot
rate coil. Terry used a circuit like this though with GEI coils and got a hot
6" (??) discharge between two coils. Beware though, go to high power and that
could knock you clean across the room!!

Pugging it into an NST will do nothing. The low resistance primary will
present an effective short to the NST output and bring the voltage down to
very little. It will still get pretty hot though!

Read all the safety lit first......
