JJ EL34 Version 2 - #05 - Mesa
EL34 II has fuller low mids and low end but does not lose headroom in the high end. Stronger than regular JJ EL34 but not as aggressive as the JJ E34L.
FAQ: If I order two or more of these tubes, are they all "the same" ?
Yes, the tubes are all "matched" and selected for the amps above.
FAQ: Can I replace the tubes myself or do I have to calibrate something?
It is not possible to make adjustments to the listed amplifiers (unless a bias setting has been installed). The tubes can therefore be replaced without any adjustment or calibration work.
