Hello,
The neon sign transformer (NST) you need is 30 mA (milliamp) at about
10,000 volt. These things are dangerous. A used one will be cheap from an
electrical repair / install company or of course a neon sign shop. If you
live in the northern parts of the country, you could also use an OBIT (oil
burning ignition transformer) for home furnaces. These are usually 23 mA
at 10,000 volts (10kv). This is what I used for my first tesla coil while
I was in high school. Do some google searches, and you'll find the tesla
coil web ring where there is lots of information about making these things.
