The JJ EL34 is a modern replacement for all EL34 applications. These tubes follow the classic EL34 sonic signature with light/fast lows, forward/singing mids, and crisp highs.
The audiophile should note that the JJ EL34 has the most relaxed and romantic overall character within the JJ EL34 family (EL34, E34L, EL34II, KT77, 6CA7). If you’re looking for the most traditional EL34 sound this is where you want to be.
Guitar players should note that the JJ EL34 has a smooth overdriven tone with a nice amount of compression when driven hard. A very vintage sounding EL34 experience. We love these in Matchless and BadCat applications, and everywhere a traditional EL34 sound is desired.
For those looking for more lows and a tighter, more modern overall character, check out the JJ E34L.
After a 24 hour burn in all power tubes are tested for noise and matched at multiple operating points for plate current (± one milliamp) and transconductance. Please leave us a note in the comments section as to what amp they’re going into and or if you’re looking for a specific grade.
