MAGNETIC AMPLIFIERS: ANOTHER LOST TECHNOLOGY

© 2000 High Voltage Press, Oregon, USA

I had always believed that first came the vacuum tube, then the transistor, period. But, thanks to an old US Navy tech manual sent in by a reader, I’ve discovered a third "lost" entity. Electronics engineers of the 1950s believed that the rugged little magnetic amplifier was going to replace the fragile vacuum tube in all its functions under a megacycle.

Originating in the USA but adopted and developed by the Nazis for the V-2 missile, the mag amp after World War II found a clique of boosters among US electronics engineers. This document, unusually passionate and well written for a military tech manual, is their promotional brochure.

Evident today only in some motorcontrol and power-supply regulator circuits, the mag amp not only can regulate but can magnify, oscillate, modulate, switch, pulse-generate, invert, convert, multivibrate, phase shift and multiply. Mag amps require almost zero maintenance, can be made indestructible, and can handle up to 175,000 amperes.
