3. Large tesla coil secondary - 24" x 5" (21 1/2" winding length) -- 21AWG magnet wire
Cost: Send me an offer  ($25.00 S&H) - I only have one available.
Specs:
Diameter of secondary coil : 5.00in
Winding height of secondary coil : 21.50in
Wire diameter for secondary coil : 0.0285in
Spacing between windings : 0.00in
Secondary turns : 754.00
Secondary wire length : 987.49ft
Secondary inductance : 14.98mH
Approximate resonant frequency : 417.10kHz
Secondary quarter wavelength resonant frequency : 249.18kHz
Secondary self capacitance : 9.72pF
Toroid capacitance required to form quarter wavelength coil : 17.52pF
--------
I'll apply 2 to 3 coats of clear polyurethane varnish on the secondary only on your request (anymore is extra). Otherwise, I will ship them with one coat of varnish (to protect against temperature change). The windings are tight and without gaps. What you see in the pictures is what you will be receiving. If you have any questions, or if you would like to purchase one, please send me a PM.
