Tube technology is a bit of a forgotten world now, although many people still remember TV sets and radios that worked thanks to those glowing tubes. The invention of the transistor changed electronics irrevocably, but even though they have great advantages over tubes, for those who value high-quality sound, tube amplifiers are still a highly desirable part of their home system.
