    Looks great, got any details on it?

    I am looking to get a 15KVa power supply and would be interested in where
    you got one from.
    Mine is for a CO2 laser though, but a Tesla coil would be nice too

    Tesla coil details:

    Primary:
    240V 4.4A to 11kV 80mA NST (neon sign transformer)
    20nF 27kV multi mini capacitor (18 x 18 series strings of 22nF 1500V
    polyfilm caps)
    ~7 turns of 0.25" soft copper tubing (30° conical spiral)
    Single air blast (for cooling and quenching) sparkgap set to about 6mm

    Secondary:
    ~800 turns of 20AWG enameled Cu wire on 6" diameter resin impregnated
    paper tube (1:4.5 aspect ratio)
    13" x 5" toroidal top load (~16pF) made from nickel plated truck
    exhaust bend donut

    I'll put some photos up on the web if it ever stops raining, it's been
    going for 4 days now!

    As for NST suppliers:

    The NST I used has been kicking around the workshop for years, but we
    did recently purchase a few smaller 6kV 24mA NSTs from a place called
    "Claude Neon", a local neon sign manufacturer.

    Check the Yellow pages for a neon sign shop near you.

    You may even be able to pick up a second hand one.

    Regards,

    Nice unit.
    What frequency does it run at?
    Did or have you trimmed your secondary coil length to the wavelength of its
    Fr?
