Transistors have many advantages over electronic tubes:

No component consumption
No matter how good the tube is, it will gradually deteriorate due to changes in cathode atoms and chronic air leakage.For technical reasons, transistors had the same problem when they were first made.With improvements in materials and in many ways, transistors typically last 100 to 1,000 times longer than electronic tubes.

Very little power consumption
It is only a tenth or a tenth of the size of an electron tube.It does not need to heat the filament to produce free electrons, as a tube does.A transistor radio needs only a few dry batteries to be able to listen for six months a year, which is difficult for a tube radio to do.

Do not need to preheat
Work as soon as you turn it on.For example, a transistor radio rings as soon as it is turned on, and a transistor television sets have pictures as soon as it is turned on.Vacuum tube devices cannot do this.After the boot, wait a while to hear the sound, see the picture. Obviously, in military, measurement, recording, and so on, the transistor is very advantageous.

Solid and reliable
100 times more reliable than the electronic tube, impact resistance, vibration resistance, which are incomparable to the electronic tube.In addition, transistors are only one-tenth to one-hundredth the size of electron tubes and give off very little heat. They can be used to design small, complex, and reliable circuits.Although the manufacturing process of transistors is precise, the procedure is simple, which is conducive to improving the installation density of components.
