Ruby EL34LCZ Power Amp Tubes Quartet
A new Tesla/JJ modified EL34 with great tone and lots of power. Very dependable. Bold bass, thick mid-range. Good high-end, not too bright. Great for the classic rock n’ roll sound. Excellent choice for Music Man amps.
Octal power tube (Max Plate Watts = 25W) The E34L has a slightly higher grid voltage rating (-13.5 to-16.5 vs -10 to -13.5 volts) than the traditional EL34 vacuum tube. Nice compression, ideal for high gain amps.
All RUBY™ Tube power tubes come already matched. There is no extra charge for this service. The Ruby Tube matching process is very exact and our tubes are matched within +/- 1 mA (mille amp) of each other.
