How long is the service life of the tube amplifier?

release time: 2021.04.22
Summary: 
In principle, the life of the tube amplifier is semi-permanent. Compared with the crystal machine, the relative life of the tube tube is determined by the electron tube. The theoretical life of the tube is not too long, generally only thousands of hours, but good tubes are used. 

In principle, the life of the tube amplifier is semi-permanent. Compared with the crystal machine, the relative life of the tube tube is determined by the electron tube. The theoretical life of the tube is not too long, generally only thousands of hours, but good tubes are used. 

How long is the service life of the tube amplifier?

Tens of thousands of hours are also very common. For example, the picture tube of a TV is a special electronic tube. Of course, many audio tubes cannot be compared with the lifespan of a picture tube. Generally speaking, the electronic tube for audio has transportation failure and early failure. Failure can be found within 1-2 months after use, or found in factory production. For electronic tubes with relatively stable quality, it should be used for 2-3 hours a day, and 2-3 years should not be a problem. Besides, the current electronic tubes are not a problem. It is not expensive nor difficult to buy. With good after-sales service, the service life of the amplifier should not be a problem, and after the amplifier is replaced, it can be rejuvenated, just like a new one. In fact, there are still many famous ones. 


Antique bulbs are sold at a high price in the market. Doesn’t it just explain the life of the tube tube from the other side? In addition, the tube tube has a strong anti-overload ability compared with the crystal tube. The crystal tube may be 1/1000 when it encounters some failures. It will be damaged in seconds, and the tube amplifier can be undamaged for a few minutes.
