A vacuum tube, electron tube, [1] [2] [3] valve (British usage), or tube (North America), [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
Russia M Grade FU81 FU81M HighPower Vacuum Tubes For Medical Apparatus
For critical preamp vacuum tube positions, in-house computer testing and matching ensures best possible tube performance. Tubes are tested at real world high voltage conditions as they would be in the final circuit. In these instances, the tube testing report is also included with t he shipped product.

The first obvious effect from too-high heater voltage is that the cathode gets hotter and the emissive material will be reacting faster and evaporating quicker, lowering the tube's effective life span.

PLATE - The part of the vacuum tube that has high voltage on it. Except in a cathode follower circuit, the output is always taken from this part of the tube. PLATE VOLTAGE - The voltage that is applied to the plate of a vacuum tube. Higher voltages give more headroom and high end; lower voltages give more breakup and a "browner" tone.

An automotive ignition coil is a special-purpose high-voltage transformer used in car engines to produce tens of thousands of volts to fire the spark plugs. In this experiment, it is used (very unconventionally, I might add) as an impedance-matching transformer between the vacuum tube and an 8 ฮฉ audio speaker.

Single triode vacuum tube on the left, note its tubular structure. The 12AX7 middle and right is a dual triode tube--two tubes in one. Pin 1 connects to the Plate (output), Pin 2 the Grid (input), Pin 3 the Cathode (source of electrons).. Rectifier Tubes. High voltage AC flows onto the plates connected to pins 4 & 6. High voltage DC current.

The medical magnetron shown here, manufactured by e2v Technologies (now Teledyne e2v), generates a peak power of 2.6 MW, with an average power of 3 kilowatts and an efficiency of more than 50 percent. Just 37 centimeters long and weighing about 8 kilograms, it's small and light enough to fit the rotating arm of a radiotherapy machine. Gyrotron

High voltage power supply safety The chief disadvantage of high voltage is the danger of burns and shock. Vacuum tubes almost always operate at high voltages, typically over 100 volts. For high power ham band amplifiers the plate voltage can be 1000 volts or even 3000 volts DC. The bad news is that this

In a modern traveling-wave tube, the beam power that is not converted to RF is recovered by the depressed collector, which acts like the regenerative brakes on a hybrid car and boosts the overall efficiency to 65 percent or more.
Machlett ML142 HighVacuum HighVoltage 100PKV Rectifier Tube eBay
Vacuum tubes generally require separate low-voltage (6V to 12V) and high-voltage (100V to 250V) power supplies. The low-voltage supply is for the tube's heater, which literally heats the tube to a temperature at which electrons will flow. High voltage is applied to the plate or anode, which attracts that flow of electrons. These voltages can.
