(1 minute)

The Medium Tesla coil is 25" tall with a base that is 18" x 24".
The 4"x22" secondary is PVC wound with #26 magnet wire.
The 13 turn, flat-spiral primary is 1/4" copper water tubing, tuned with a clamp.
The toroid is a 12" x 3" spun aluminum from Information Unlimited.
The cap is a 0.015 uF @45 KV Maxwell.
The power supply is a 14.4KV (1.5 KVA rated) Potential Transformer.
Current limiting is provided by a 500 foot roll of 12 Gauge wire.
