Pentode is a thermionic valve (a vacuum tube) with five electrodes. Invented in mid-1920s, it remains in use today!
Here's a little song I wrote. It is an electronica/progrock fusion in 5/4 time most of the time, hence the name :)

Playing with pentodes

Playing with pentodes: More microphonic than triodes but they still sound great. #tubes #valves #vacuumtubes #elecrontubes #triode #pentode #tone

Audio sweep tests of a 3-stage subminiature pentode preamp for harmonica that I'm building for a buddy. This was a little while ago, and changes have been made since the recording. The project is currently on pause.
