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. Our Magic Parts matching process is very exact and our tubes are matched within +/- 1 mA (mille amp) of each other.
We can supply tubes in matched pairs (MP), matched quartets (MQ), matched sextets (MS) or other groups as requested.
If you order two tubes, we will ship them as a MP. If you order four tubes, we will ship them as a MQ, and so on.
If you have any special requests, for example if you want 12 tubes and they should all be MP and no MQ, please enter that in the Special Request box on the checkout page.
