Availability: Usually ships within 24 hours.

USD $‎23.95

Need matched power tubes? Don't worry! Price includes matching in any quantity you need for no extra charge. Need a matched pair? Just order "2" tubes. For a matched quad order "4" tubes. Matched sextets and octets are available as well.

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 vacuum tube, "the EL84EH tube faithfully recreates the classic Mullard design. Tri-lam plate material and selected screen wire increase thermal dissipation. The EL84-EH vacuum 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.

Electro-Harmonix EL84 | EH-EL84


My H & K Tubemeister 20 Deluxe sounds better to me with these EH EL84s.
There's a bit more headroom on the Lead channel and I find the overdrive less harsh than it did with the stock JJ's

Electro-Harmonix EL84 | Won't last long


Great tone, but died after 2 weeks. My amp kept blowing the HT fuse. After some troubleshooting, I found out it was the EH-EL84 set I just purchased from this company. Never had issues with JJ or GT's.

Electro-Harmonix EL84 | Outstanding EL-84’s for Orange Rocker 15

by -

Put these EH-EL84 tubes in my Orange Rocker 15 which replaced the Groove Tube EL84’s. My amp came alive, the tone was what I was searching for! Fast shipping and great service from the tube store made it a pleasant shopping experience.

Electro-Harmonix EL84 | Great Product


Just got these EH-EL84 today. What a difference!
My Kustom 15 Defender sounds fantastic now.

Electro-Harmonix EL84 | Reliable and affordable


These EH-EL84 tubes 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 Electro-Harmonix 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 of EL84 tubes 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.
