Abstract

The invention discloses an audio power amplifier of an electronic tube. The audio power amplifier of the electronic tube comprises the electronic tube, a bracket and a guide rail. The guide rail is located in the bracket and is arranged along the vertical direction. The bottom end of the electronic tube is located on the guide rail in a slidable mode. The electronic tube is enabled to be located above the bracket by sliding the electronic tube. A ball screw is arranged in the bracket along the vertical direction. The bottom end of the electronic tube is connected with the ball screw through a shaft sleeve. A motor is fixed at the bottom of the bracket. A motor synchronizing wheel is fixed on the rotor of the motor. A screw synchronizing wheel is fixed at the bottom of the ball screw. The motor synchronizing wheel and the screw synchronizing wheel are connected through a transmission belt. According to the power amplifier, the problems that damage is easy to cause and the service life of the audio power amplifier is reduced due to the fact that the internal electronic tube of the general audio power amplifier is externally arranged are solved.

Description

technical field [0001] The invention relates to an audio amplifier, in particular to an electronic tube audio power amplifier. Background technique [0002] The audio power amplifier refers to the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source to drive the speaker to emit sound. Referred to as power amplifier, commonly known as "amplifier". The tube inside the ordinary audio power amplifier is easily damaged due to the external installation, which reduces the service life of the audio power amplifier. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide an electronic tube audio power amplifier which can effectively protect the electronic tube and greatly increase the service life. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide an electronic tube audio power amplifier, which solves the problem that the int...
