Convection Cooled Single Gap System
Excellent for Tesla Coils up to 12"
Intended for Tesla coils up to 9kV at 60ma. Uses ¼" pure tungsten electrodes mounted on aluminum heat dissipating fins. Horizontal retaining screws provide easier access and adjustment of spark gap width. Base is polycarbonate with mounting holes. Includes high current connection lugs. Size is 5½" x 2 x 2". Used in our BTC30 giving 14” sparks.
We also carry solid copper block holders or the more attractive PANDUIT holders. We tested for temperature rise and peak current and found no difference between the lower cost aluminum or copper holders.
