Ruby Tubes
JJ EL84 Matched Tubes
The most powerful EL84. Much like the GE6BQ5.
Hands down the best 84 out there.
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.
6 month warranty on all tubes
