Tube Amplifier KnowledgeVacuum tubes, in most people's minds, were popular when Grandpa was young. Why did it become popular again? And I heard that the sound is great, and it is played by rich and tasteful enthusiasts. The above seems to be most people's impression of vacuum tube audio. Is it so di

Basic knowledge of HiFi amplifierFor a complete HiFi audio system, in addition to a pair of speakers you are satisfied with, the matching power amplifier is also essential. The power amplifier in the HiFi system is not only as simple as adjusting the volume and driving the speakers, but also has man

Take you to get started with tube amplifiers Amplifier ComparisonFeatures and StructureTransistor amplifiers work at low voltage and high current. The working voltage of the power amplifier stage is within tens of volts, and the current reaches several or tens of amps. In circuit design, direct-cou

Tube amplifiers work under high voltage and low current conditions. The plate voltage of the final power amplifier tube can reach 400-500V or even thousands of volts, while the current flowing through the tube is only tens to hundreds of milliamperes. The input dynamic range is large and the convers

The difference between tube power amplifier and transistor power amplifierAccording to the different types of power amplifier tubes, power amplifiers can be divided into tube power amplifiers and transistor power amplifiers. As early as the 1960s, tube power amplifiers had been popular al
