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).
