The shortcomings of the power amplifier of the electron tube
Date:2018-05-18 Num:1541

1, the life of the electron tube is relatively low, and after some one thousand or two thousand hours, some technical indicators are obviously reduced.

2. The electronic tube amplifier has high power consumption and often works in the class a state, which reduces the efficiency, but does not have the harmful sound quality such as transient intermodulation distortion, switch distortion and cross distortion.

3, the tube amplifier has no advantage over the transistor amplifier in terms of weight, efficiency and life.

4, in use, the electronic tube should have good ventilation and heat dissipation, the temperature overheating will inevitably shorten the life of the electronic tube, so to make the tube as much as possible to keep the lower temperature.

5, the electron tube is afraid of vibration, so it is also important to take precautions against vibration and avoid vibration as far as possible.
