The EL34 is a type of vacuum tube (or thermionic valve) that is commonly used in audio amplification equipment, particularly in guitar amplifiers and high-fidelity audio systems. It is a power pentode tube, which means it has five active elements (cathode, anode, and three grids) and is designed to amplify electrical signals.
