You might think the vacuum tube has burned itself out of electronics, but its filaments are still burning brightly in certain quarters. Many electronics enthusiasts still have a love for vintage tube-type gear and consider it to be among their most prized possessions. How about you? Do you work with vacuum tubes? If so, what is your favorite application?

What say you?
