The reality of valve and transistor amplifiers

Back in December, the Hi-Fi Hobbyist podcast took a first look at the use of valves and transistors in Hi-Fi components. Valves or strictly thermionic valves are the British terms for what U.S. Hi-Fi Hobbyists call vacuum tubes. We will use the term “valve” throughout these podcast episodes.

In this series of episodes, we are taking a deeper more detailed look at the topic. In last week’s episode, we looked at the underlying scientific theory, and the theoretical implications for sound quality.

In this week’s episode, we will start by looking at examples of real-world amplifiers and then consider why the reality is more complex than the basic science might suggest.

In the final episode, we will feed the data to two AI protagonists and let them debate the merits of valves and transistors.

In this episode, the music accompanying the podcast is music created by the Hi-Fi Hobbyist with the help of Mureka AI to evoke the rock and pop music from the 1970s and 1980s.

It starts with a largely acoustic track that borrows from the roots of rock and roll, before gradually moving on to different forms of rock, first southern rock, then the kind of smooth rock that characterised many American bands in the 1970s, before finishing with a good old British style rock track. This kind of music has traditionally been thought to be better reproduced by transistor amplifiers than valve amplifiers.
