BM7 Tesla coil Gallery
The BM7 coil was a coil in transition, it started off using a sync rotary spark gap given to us by Steve Crawshaw, it uses a new 6" secondary with a height of 26.5", using our modular MMC tank capasitor and an old radar/radio transformer 8.5Kv at 350mA (It`s an oil filled unit)
