Typical HT supply circuit schematic. The HT supply was usually obtained from a full wave rectifier circuit similar to the one shown. In those sets that had no mains transformer (the so-called AC/DC design), the HT was obtained directly from the mains supply, either with a simple half wave rectifier or with a voltage doubler circuit.
The following group of digits indicate the power: Backward-wave amplifier or Traveling-wave tube: Output power; 2nd letter: A – in mW; 2nd letter: B – in W; Klystrons: Output power in W; Reflex Klystrons: Output power in mW; Magnetrons: Pulse output power in kW; Continuously transmitting tubes: Maximum anode dissipation in W or kW in Class ...
In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
So-called "All American Five" vacuum tube radio receivers used a power supply that could work on either AC or DC. An AC/DC receiver design is a style of power supply of vacuum tube radio or television receivers that eliminated the bulky and expensive mains transformer. A side-effect of the design was that the receiver could in principle operate ...
"Full-wave" versions with two separate plates were popular because they could be used with a center-tapped transformer to make a full-wave rectifier. Vacuum tube rectifiers were made for very high voltages, such as the high voltage power supply for the CRT of television receivers, and the kenotron used for power supply in X-ray equipment.
Two 833A's are capable of approximately 800 watts sine wave power in a class B audio amplifier or modulator. This assumes approximately 58% efficiency, 1400 watts input, and 300 watts per tube anode dissipation. The anode normally shows a dull to medium red color when operating at full power. [2] The tube is supported solely by its two filament ...
