Problems solved by technology

[0002] The current electronic tube 300B single-ended amplifier uses WE310A as the driver for the front stage. Through capacitive coupling, WE310A is a side heat pipe, which is not conducive to weak signal amplification, and capacitive coupling is not ideal for signal transmission. The filament power supply of electronic tube 300B is lit with AC, which is noisy. Lighting up with ordinary rectified DC, the sound quality is still not ideal

Description

technical field [0001] The invention belongs to the technical field of electronic tube amplifiers, in particular to a Hi-end electronic tube amplifier circuit. Background technique [0002] The current electronic tube 300B single-ended amplifier uses WE310A as the driver. Through capacitive coupling, WE310A is a side heat pipe, which is not conducive to weak signal amplification, and capacitive coupling is not ideal for signal transmission. The filament power supply of electronic tube 300B is lit with AC, which is noisy. Lighting up with ordinary rectified direct current, the sound quality is still not ideal. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a Hi-end tube amplifier circuit with high signal-to-noise ratio and large dynamic range. [0004] In order to realize the above functions, the technical solution adopted by the present invention is as follows: a Hi-end electronic tube amplifier circuit, comprising a...
