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.

Great sounding tubes


Just had 8 of these put in my acoustic masterpiece AM-201H and wow. Compared to the OEMs, for which I could not find the manufacturer, these Tubes have higher highs and better bass response. I'm a happy camper.



These are a well made tube like other EHX stamped stuff I have used (I have only had one bad one and that was a microphonic 12ax7eh). No rattles out of the box unlike some JJs I have had. They are punchy and add a nice rounded feel to a driven tone when you push them hard, almost like a really mild fuzz but creamy and not brittle like a Sovtek can get. I like them a lot. El84s all seem to rattle a lot in a combo but so far no issies with these.

Great value!


I really like these EL84's. They are durable, sound good, and are priced competitively. I'm currently using a pair in a Smokin' Joe II Amp.

reliable and affordable


These really don't cost much at all, not much more than standard sovteks. But they seem to last really well. I have pushed them hard in one guitar amp and they just work with no signs of wear and importantly, no tube rattle (I have had loud rattle from sovteks and JJs in combo amps but not these).

I have a quad from 2006 still going strong in another amplifier. 2006. It's a combo ac30ish oven-type amp. I had the amp serviced recently and during a power test it was spot on. It also sounds quite perfect and performs beautifully even when run hard for hours. I really don't have much else to say, this is insane service from cheap tubes.

Great Product


Just got these today. What a difference!
My Kustom 15 Defender sounds fantastic now.
