The Making of an Entry-level Tube Amplifier

Today, with the rapid development of electronic technology, the old vacuum tube has been gradually replaced by transistors or integrated circuits with small size, low power consumption and long life in most areas of the electronic world, but it still occupies a place in the audiophile world with its charming sound. Many audiophiles want to assemble a vacuum tube amplifier by themselves. Relive the warmth of yesterday's tube sound. However, considering that most young people have little knowledge of "vacuum tubes" in the early stage of audiophile, I would like to recommend a beginner's tube amplifier production to everyone.
