Abstract

The present invention has opened an eletron tube phase reverse amplification circuit used for electron tube push-pull power amplification circuit to the public which includes two amplificatino units and direct-coupled differential pressure connection being applied in between two units. The present invention utilizes the strong point of traditional phase reverse circuit and overcomes the shortcomings of phase unbalanced in output signal of traditional phase reversal amplification circuit so that it has the advantages of circuit in simple structure, high efficiency of amplification and stable performance for to be used widely in power amplificatino of high fidelity sound appliance, radio emission and all kinds of electron tube fields required high efficiency and high accuracy.

Description

field of invention [0001] The invention relates to an electronic tube inverting amplifying circuit, in particular to an electronic tube inverting amplifying circuit applied to high-fidelity audio power amplification and some radio transmissions requiring high efficiency and high precision. Background technique [0002] The electronic tube is the oldest electronic amplifier device. In the late 1950s, due to the appearance of the transistor, the electronic tube was almost eliminated, but today, it is not possible to completely withdraw it from the electronic field. First of all, in the audio industry, people In the long-term use of transistor power amplifiers, it is generally found that transistor power amplifiers are difficult to replace tube power amplifiers in terms of sound quality and timbre, especially in terms of the artistry of sound performance, and there are some factors that affect sound quality that are difficult to overcome. In the popularization...
