A vacuum tube triode is an active electronic component that used to be commonly used in amplifiers and other electronic products. I say used to be, because it has generally been replaced by transistors in modern electrons. However, there still remain a few applications where vacuum tube triodes is still used today. One of those applications is in the preamp section of audio amplifiers. Another is in the power amplifier section of audio amplifiers. Triodes are still used in audio equipment these days because they have pleasing distortion characteristics compared to transistors. Triodes and tubes in general are also still used in applications that deal with either very high frequencies or very high power levels, such as radar and other microwave equipment, as well as high power radio transmitters.
The triode is just one type of vacuum tube. There are many different types of vacuum tubes, including rectifiers, diodes, tetrodes, pentodes, hexodes, heptodes, and combination tubes that may include multiple unites of the same type of tube or a combination of different types of tube all enclosed in one unit. Triodes may be either signal amplifiers or power amplifiers. Signal amplifiers are used mostly in preamplifiers, while power amplifiers are used in mostly power amplifiers. The difference between the two is that signal triodes amplify voltage, while power amplifiers amplify current.
A basic signal triode contains four elements, a heating coil along with three other elements called electrodes. The three electrodes are called the cathode, the control grid, and the anode. The anode is also commonly called the plate. Triodes are built starting with the heater coil, then the cathode, usually made out of sheet metal, is immediately wrapped around the heater coil. The control grid, usually made out of wire, is then wrapped around the outside of the cathode, a small distance away from it. Next the plate, which is usually made out of sheet metal, is then wrapped around the combined heater, cathode, and control grid assemble, at a somewhat larger distance form the rest of the components. Next, the whole combination is then enclosed by an envelope made out of either glass or metal, usually glass. A number of contact pins run though the enclosing envelope, so that the internal elements of the triode may be connected to the circuitry of any electronic device, in which the triode is to be used. Lastly all the air inside the envelope is pumped out, and the envelope is sealed.
Power triodes are constructed a little differently than signal triodes, generally they are bigger and heavier. Also in power triodes the heater coil may be omitted. When this is done, the cathode is constructed in such a way that it heats itself.

Benefits of tube amplifier
Since many prefer the tube amplifier because of the way the sound responds whenever you play a note, it is better than the digital ones. According to many musicians, they make the sound notes that we play sound better, cleaner and smoother. The sound which it gives out is more natural compared to the other amplifiers and that's the main reason they are preferred over the digital ones, especially for instruments such as a guitar.
Magnetic Line amplifiers
Magnetic Line provides a wide range of tube amplifiers which provide a great sound quality along with great amplification. These amplifiers are handmade and of great quality. They are well-made and durable. They also come with a remote control along with a tube cage which is a great offer that they provide. The circuit is well constructed and well wired, the factors which make them one of the most durable products. It comes with an EI transformer which is specially designed for the power supply.
These amplifiers are best if you are a musician and need a good quality amplifier. The output of this amplifier is great and natural compared to other types of amplifiers. The Line Magnetic 518ia is one of the best models available. It is a class A amplifier which is something that people recommend. The amplifier is single-ended and comes with a remote control. It also comes with a tube cage cover and is available in two different types of colors. One of them is black and the other is gold which is only on the front panel. The voltage needed is the standard voltage which is 220V- 240V. The amplifier is heavier than the standard one which is 35 kg but provides a better sound quality in return.
