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.

LAME! The old Czechoslovakian Tesla tubes had special tubes that used black light tinted glass for making their tubes a truly cool groovy very deep dark violet blue color, and if you were super lucky you could also get rich a deep dark read heat lamp/chicken coop tinted glass too, from Tesla. Those colors were so dark and rich looking, but these tubes are just really poor knockoffs, with a slightly blue tinted glass. If JJ would just buy some UV lamp cullet glass & get the right coloring to give these that black light UV lamp tint, they could charge $20 extra, and I'd pay it. Lately their glass has been so poorly annealed, why not just buy a boat load of black light glass cullet from China? I have had over a dozen JJs break at the base, with a circular crack in the glass, indicative that they are not annealing the glass properly. The heat makes it crack. I suspect they may be using Chinese glass now anyway, rather than their European glass, and it needs a different lehr treatment. I am surprised that Sino Shuguang hasn't made some hi fi tubes from black light glass or chicken coop glass.

I like the JJ EL34L's, and the blue glass is cool. :) I build amps, so I order periodically from you guys and will continue to do so.
