Vacuum tube is a tube that is made of glass in which gas has been removed therefore creating a vacuum therein. For electricity to flow smoothly, electrodes are important in the vacuum tube to ensure the flow is consistent. Vacuum tubes were first used in computers for amplification but as time went by its uses were also used in radios, televisions and telephones. The size of a vacuum tube is large which does not fit the modern computing equipment available which has greatly led to decrease in their usage. Currently vacuum tubes are used in big machines such as audiophiles. Below are some of the methods that one can use to identify different types of vacuum tubes.
This is a special tube that is used to tune the television. Not all persons love high volume hence for them, this kind of vacuum tube would be better as the noise is reduced.
This type of tube is soft and has a lower tone making it suitable for guitarists. It is ideal for maintaining the tone and shaping it giving one the ability to control themselves. To get the best result, the correct tube must be used in guitars to produce clear tones of which swapping the vacuum tubes will lead to a difference in the outcome. There is a slight similarity between 12Ax7 and 6SL7 hence they can be used together where the other one is not available. This particular type of vacuum tube stands out from the rest due to its ability to have a clean single sharp note.
KT88 is another type of vacuum tube that has high power which is good for hi-fi amps. Due to its capacity of holding high power, its own in this particular grouping and can withstand high voltage. 6L6 is characterized by its ability to produce rock sound with low music which makes it known and used for different applications.
6V6 is a form of 6L6 but in a reduced form and has been used for a long time. This type of tube has quite a low volume making it to be mostly used in preamps. These tubes are mostly used for marshal amps because of their low power usage.
EL84has a great volume and good for blues and rocks. When overworked, it produces great work than ET34 and it has been improved to date. Because of 6550’s nature of being versatile, it has been accepted and commonly used for both guitars and stereo amps in most of the equipment.
Different vacuum tubes produce different sounds which will depend on the quality that one needs and according to the tone too. It is advisable to select the best vacuum tube that will serve the best purpose.
