Sample 1: Anode Transformer Modulation Stage Using a Tetrode

Electron tube circuit sample: This sample demonstrates the AM plate modulators. In plate modulated systems, the voltage applied to the stage varies. Since the available output power depends on the supply voltage, it is modulated. transformer to change the anode voltage. can be applied for this purpose. The advantage of the transformer method is that the sound power can be fed into the RF stage and converted into RF power.

Sample 2: Audion Circuit

Electron tube circuit sample: This sample represents the Audion circuit. The Audion is an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906. The Audion tube allows the detection and amplification of weak radio signals. As the first triode vacuum tube, the Audion revolutionized radio broadcasting--and made it more practical.

Sample 3: Audio Triode Cascode Circuit

Electron tube circuit sample: This sample shows an example of a cascode amplifier with a common-source amplifier as the input stage. The cascode (a contraction of the phrase cascade to cathode) is a two-stage amplifier composed of a transconductance amplifier followed by a current buffer. In valve circuits, the cascode is often constructed from two triodes connected in series, with one operating as a common grid and thus acting as a voltage regulator, providing a nearly constant anode voltage to the other, which operates as a common cathode.

Sample 4: Backward Wave Oscillator

Electron tube circuit sample: This sample shows the Backward Wave Oscillator (BWO) circuit. BWO is used only for amplification and contains a helix as a delay line. A wave runs on this and interacts with an electron beam. However, the generated wave runs backward in BWOs on the helix, i.e opposite to the direction of the electron beam.

Sample 5: Battery Circuit of a Triode Vacuum Tube

Electron tube circuit sample: This example shows the Battery Circuit of a Triode Vacuum Tube. Three different voltages are generally required, using three different batteries designated as the A, B, and C batteries. Each battery has a different designation depending on which tube element it was associated with.

Sample 6: Beam Deflection Tube Circuit

Electron tube circuit sample: This is an example of a beam deflection tube circuit. A beam deflection tube is a vacuum tube with an electron emitter, a beam intensity control grid, a screen grid, occasionally a suppressor grid, and two electrostatic deflection electrodes on opposite sides of the electron beam. It can be used as two-quadrant, single-balanced mixers or (de)modulators with linear qualities. The cathode and the first two grids can be made into an oscillator. Two beam deflection tubes can be combined into a double-balanced mixer.

Sample 7: Blocking Generator

Electron tube circuit sample: This sample shows a blocking generator circuit. The blocking generator is a relaxation oscillator with deep transformer feedback. It outputs pulses of short duration with a long repetition period. It can operate in auto-generation and standby modes.
