The most powerful EL84. Much like the GE6BQ5. Made in Czechoslovakia.
Great compromise between tone and reliability. Nice mids, sparkling highs and solid bottom end. They can take the heat and vibration in stride without any negative tonal effects.
Ruby's matching process is very exact and our tubes are matched within +/- 1 mA (mille amp) of each other.
