extra high tension

EHT or Extra High Tension, the accelerator supply to a cathode ray tube.

John explained his construction techniques and ideas he had when building his Extra High Tension Generator, which is normally known as a Plasma Ball.

EHT or extra high tension similarly describes the accelerating voltage for a cathode ray tube such as used in a television, computer monitor or cathode ray oscilloscope.

A total of 63 kilometre new transmission lines have been laid down enhancing the network from 1186 to 1249.32 kilometers, while 124 kilometer extra high tensions lines have been rehabilitated.

It was soon superseded by the B18T, which used an extra high tension transformer (EHT) developed by German companies before the war to produce high cathode ray tube voltages.

Some larger models such as the KV-1320UB for the United Kingdom market were initially fitted with 3AT2 valves for the extra high tension (high voltage) circuitry, before being redesigned as solid state in the early 70s.
