Top 10 Radioactive Electronic Tubes

By Radu Motisan December 30, 2012

Some of these tubes contain small quantities of Cesium-137, Cobalt-60, Radium-226, Krypton-85. The radioactive elements have been added to increase the electronic response by improving the internal ionization processes.

Tube: TGI2 400/16 (ТГИ2-400/16), Russian hydrogen thyratron

By Radu Motisan October 9, 2011

A hydrogen thyratron is a device capable of switching big amounts of energy. The major advantage over other thyratrons is that the deionization time is reduced by using the hydrogen gas, generated in a small reservoir inside the tube, from a metallic Hydride.

Vacuum tube tesla coil (VTTC) using Russian GI-30

By Radu Motisan April 11, 2011

A vacuum tube tesla coil built around the Russian tetrode GI-30. My first VTTC and my first vacuum tube circuit, and some very rewarding results.
