A Spectacular Electrical Arc Display!
This is a spark driven Tesla coil generating highly visual and audible sparks into open air without a return contact. It operates from a standard 115V wall outlet.
|This item is assembled and ready to use.

With twice the output power of the BTC40, this classic core & coil design throws long sparks of electricity into the air, and is still able to run from a standard wall outlet.
This is a larger and heavier Tesla coil than our BTC40 that requires 2 people to move, but is still small enough to be operated on a tabletop (although it will pretty much dominate the table).
A heavy piece of wire is connected to the front panel of the unit for grounding to a dedicated lead if necessary. A grounded strike ring prevents the long electrical arcs produced by this coil from arcing to some of the sensitive electronic parts and pieces. Bypass capacitors are placed across both the neutral in the hot AC line and connected to the third wire grounded lead.
The spark gap is air-cooled with a high output muffin fan and uses three 2 x 3/8” pure tungsten electrodes that rarely requiring cleaning or dressing. The tungsten electrodes are easily adjusted to help vary the length of the output discharge. This can be used to increase or decrease the recommended time of running your coil.
Hardware is all brass where required with the primary coil being all copper tubing.
The kit contains a pre-wound and fully prepared secondary coil and all parts to complete the unit, including an 18 x 5 inch toroidal terminal which greatly adds to the performance and overall appearance of the completed system.
All our Core & Coil Tesla Coils use special built “beefed up” capacitors intended for optimum and long term reliable performance. They also use transformers with special “beefed up” internal secondary HF chokes wound to block damaging voltage transients. This eliminates breakdown when used with the proper value external resistors (included).
Power enough for most R&D experiments. Kit and assembled units include wound coil (so you don't have to do the winding), multi-section spark gap, and large 18" toroid terminal. Individual parts also available.
Assembly: Mostly mechanical assembly with some soldering
Applications: Use as an advanced science project, museum display, special effects prop, and research (such as the electrical confinement beaming of high frequency electricity for weapons), and other uses.
This Tesla coil is built using transparent polycarbonate to reveal the inner wiring. This is truly a spectacular looking device!
