This TAD selection of the original Svetlana EL34 is very dependable and a recommended choice for combo amps.
Somewhat lower power but nice balanced tone with fine heights, very detailed and musical mids and not too much bass. The TAD EL34-SVT is selected out of the original Svetlana-Factory production in St. Petersburg (winged -C- logo). The TAD EL34-SVT is indentical to the stock tube used by Marshall for the JCM2000 TSL/DSL series. It is the only EL34 version we do recommend to use with this amp models.
