The Electro Harmonix EL34EH is one of the most musical EL34 available today. It is powerful without being harsh. It is the perfect replacement for older guitar amps as well as modern Hi-Fi amps. The EL34EH is the perfect mix of balanced tone with good power.
Superior "Black base" high-voltage power pentode. Perfect EL34 for vintage equipment and for improved performance of modern amps. Extremely musical and predictable, with a sound that is rich, smooth, and detailed without being edgy.
