Vacuum Tube - E34L, JJ Electronics, Blue Glass
Blue glass envelope.
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

I bought a matched pair of these tubes two years ago from your company with 31ma marked on the tube box. I did not use these tubes. now I want to buy another matched pair to achieve a matched quad for my push-pull amplifier. Is it possible?

Staff MemberTop ContributorAll JJ tubes are now matched using our new Apex Matching System and as a result we would not be able to match numbers from our previous matching system.

I have two Marshall TSL 100's. Can you recommend which matched EL34 quad set to purchase to get the best sustain, EVH "brown sound", general "heavy metal" type tones usually used in modern rock.

The E34L will have more headroom compared to EL34's. You can request "low numbers" when ordering to allow for quicker breakup.
