Vacuum Tube - EL34, Electro-Harmonix
Superior "Black base" high-voltage power pentode. Most common power pentode found in British amplifiers such as Marshall, Hiwatt, Laney, and Sound City. The EL34EH defines the classic British rock sound of the 1960s and 1970s. 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.
- Originally found in vintage British amplifiers such as Marshall, Hiwatt, and others
- Also suitable for HiFi
- 6CA7 equivalent
According to the technical journal, Vacuum Tube Valley, "The Electro-Harmonix EL34EH is balanced throughout the entire music spectrum. Bass goes deep and is tight, mids are sweet and well defined, and highs are detailed and extended."
