1. Amplidyne, up 2 1 / 8 at 12 1 / 4
2. World War II saw the development of electrical fire-control servomechanisms, using an amplidyne as the power amplifier.
3. An "'amplidyne "'is an electromechanical amplifier invented prior to World War II by Ernst Alexanderson.
4. Mk . 37 director train ( bearing ) and elevation drives were by D . C . motors fed from Amplidyne rotary power-amplifying generators.
5. This turned the machine from a voltage-to-current amplifier into a voltage-to-voltage amplifier, and they called the new variant an Amplidyne.
6. The amplidyne's frequency response is limited to low frequencies, it cannot even handle audio frequencies, so its use is limited to amplifying low frequency control signals in industrial processes.
7. Although the train Amplidyne was rated at several kilowatts maximum output, its input signal came from a pair of 6L6 audio beam tetrode vacuum tubes ( valves, in the U . K . ).
8. The vacuum tube was the only amplifying device ( besides specialized power devices such as the magnetic amplifier and amplidyne ) for 40 years, and dominated electronics until 1947, when the first transistor, the BJT, was invented.
9. Vacuum tubes of reasonable size were unable to deliver enough power to control large motors, but vacuum tube circuits driving the input of an amplidyne could be used to boost small signals up to the power needed to drive large motors.
10. Supervising development of aircraft equipment during the war, he devised important fire-control systems used by B-29s and what turned out to be an even more important development, the first military and commercial applications of amplidyne generators, devices for regulating and controlling electrical power.
