Well-suited for museum displays, university research, laboratory studies, and the advanced hobbyist familiar with the use of high voltage. The complete BTC70 comes ready-to-use with all components: the power supply with transformers, chokes, and 20 feet of HV cable (to operate the coil from a safe distance); the base unit with capacitors and spark gaps; the fully-wound secondary coil; and the toroid. The coil stands over 6-½ feet high, and requires a dedicated 220vac 50amp single-phase 3-plug "utility" socket (not a standard 115V wall outlet like our other coils).
|Paper plans: 47 pages of color photos, engineering drawings, schematics, a parts list, etc., so you can build this coil for less than the Assembled price (but with several days of work required). All specialized parts are available through us and are fully described on the parts list (also available as downloadable plans for roughly half the price).|
