Vacuum Tube - E34L, JJ Electronics
The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.
Matched versions of this tube use Apex Matching
Choose burned-in tubes for maximum stability and performance.
RoHS Compliant
