At the close of the Nineteenth Century, research as conducted by Nikola Tesla became exceedingly directed towards high vacuum – high frequency vacuum tubes. Tesla produced a variety of single electrode lamps, some of which manufactured rather unique rays, dubbed as Shadowgraphs, akin to that of X-rays.
At G.G. Brock Laboratories, a more improved patented derivative of Tesla’s original Shadowgraph Tube has been developed, being the first of its kind. The 1A21 radiating beam tube is simplistic in construction, possessing only a single light-element cathode electrode, encased within a glass envelope exhausted to a vacuum of 10⁻⁷ Torr. The tube is supported by a strong dielectric tube base, with a banana style base pin, making it convenient for the experimenter to hook it up directly to any power supply.
The tube is powered by providing high frequency alternating currents of disruptive discharge character to the base of the tube, ultimately setting the tube into action. The 1A21 may be directly powered by units such as a Tesla Coil, Oudin Coil, Diathermy Apparatus, etc. This tube will not operate on direct current supplies, as the molecular action within the tube is solely dependent on high frequency impulses.
Note, that each tube is handmade from scratch, meaning there will be a lead time of two to three weeks for a tube order to be completed upon placement of order.
