The MESA/Boogie EL-34 STR-447 power tube is our very best overall EL-34. It is a premium grade, NOS (New Old Stock) equivalent and our tube of choice in the production of all new Mesa EL-34 powered models. It has a traditional EL-34 tone & feel that is very urgent and aggressive and is an excellent choice for all styles of gain, especially classic rock, alternative rock & metal. This tube is true to the crown with a focused low end, crushing mid range crunch and crystal-like highs. This is one of our favorites for authentic British tone. Excellent structural quality provides exceptional consistency and reliability.
