What is even more important, is the fact that they are NOT
rated for continious usage. Most have a 3 minute limit and
believe me, if you don�t heed this printed (on the label)
warning, you will get one hot xformer. Also don�t expect
these kinds of xformers to last very long. A NST is quite a
bit more robust.

Tobias: Call every sign shop you can find and bug them until
you find a shop that is willing to part with an NST (it might be
a prob if you aren�t 21 years old). Tell then what you are
building, that you are a student, etc. That usually helps.
Germany uses the 7.5-8kV flavor, but that won�t stop you
from making big sparks, as I have proven ;o)

Me too ;o)

P.S: Where are you situated, Tobias?

Coiler greets from Germany,
