Finally, an Electro-Harmonix version of the EL84 power tube. Expect them to take the heat in AC30 amps. Electro Harmonix says this about their tube, "the EL84EH tube faithfully recreates the classic Mullard design. Tri-lam plate material and selected screen wire increase thermal dissipation. The EL84-EH tube is a remarkable reproduction of a vintage tube that is capable of maintaining its sweet and musical tone under any voltage conditions."

Note: These tubes have a slightly larger diameter than other EL84 tubes so they can not be installed into some '90's era Marshall DSL201 or DSL401 amplifiers, some '90's era reissue Vox AC15 amps, and Bad Cat amps.

Long lasting tubes


Years ago I replaced a set of JJ that went bad on me with a quad of these in my Classic 30. While the sound of the JJs was a bit sweeter and more harmonically complex, they lasted months while the EH EL84s lasted YEARS. I just replaced them with Tung Sol because one went bad. The Tung Sol are little brighter and have more juice, but they're also new so some of that's to be expected. Anyway, these suckers took the heat and vibrations of my Peavey C30 for a LOOOONG time. If they're still made that well today, the price for a matched quad is a bargain. If the Tung Sols can't take the torture in my amp, I'll get another set of the EHs.

Very good tubes


I installed these in my Tubemeister 18 Head & Voilà...these tubes are very well balance...Better than these tungsol tubes....

Excellent in Peavey Classics


Put these in my old Classic 30 along with 2 EH 12AX7 and one Tung-Sol 12AX7 on the clean. Sounds awesome, thick and very musical. Much better than JJ. Peavey Classic with JJ sounds odd and never satisfying, but EH sounds great for the price.

Vox AC4C1-12


The JJ EL84 sounded loud and shrill. JJ 844 was too compressed. Sovtek full but a tad shrill. The EH very musical, tamed the highs and was my favorite of the four.

Crate VC50 Head


Nice sounding tube. It got everything I want for this type of tube. Going to get a set for my dad's old Vox AC30 (65 mod) soon.
