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.

Good quality and nice design, but the plexiglass is a bit too flexible (needs to be thicker). Exact adjustment with narrow gaps is not easy because of the flexibility.

Before buying this spark gap my circuit would not supply enough current to light up an incandescent bulb. But after hooking this in the circuit big current came out of the Tesla Pancake Coils.
