Ruby EL84CZ Power Tube Matched Pair JJ
The most powerful EL84. Much like the GE6BQ5.
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.
All RUBY™ Tube power tubes come already matched. There is no extra charge for this service. The Ruby matching process is very exact and our tubes are matched within +/- 1 mA (mille amp) of each other.
