      Electro-Harmonix

      These are Electro-Harmonix EL84EH power tubes in platinum matched sets. The EL84 is the most common low power pentode tube, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Delivers quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.

      Electro-Harmonix' platinum matching process consists of a 24-hour tube burn-in period followed by a bias (plate) current measurement in milliamps.

      Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. In comparison, hard-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion, while medium-rated tubes fall in between.

            I ordered these tubes to change out the ones in my stock Bugera V22 amp with great results! My amp tended to be a little muddy and didn't have good tonal separation. These guys definitely helped to improve it's overall musicality. Worth the dollars....

                      I have cathode biased Goodsell Super 17 and I play through it all the time. Every few months I install a new matched set of hard el84eh tubes. Clean, sweet, crisp tone.

                      I replaced all the tubes in my amp.i used 4 of these EL 84's. on this manufacturers website is listed that this tube is a perfect stock replacement for VOXac30. Though not made in china like my originals they sound exactly the same. Perfect stock sound.

                      It's still early in the honeymoon period but these tubes brought my Laney VC30 back to life. I imagine it's like new tires on a car. Any new set will feel great compared to the old worn out set. These tubes increased the bass response, over all volume & timbre and the 60 cycle hum is gone. I say worth it!

                      Re-tubed a Fryette Memphis with these. Bright and crunchy compared to JJ's. I like these. Retain the chime without harsh highs. Tight low end. Competively priced too.

                      Good investment in better sound
                      I purchased these for my 1995 Blues Junior and they really seemed to open up the sound. This sort of thing is always subjective but my guitar teacher who has been in the busienss for years loved the change also. The amp seems more open and more responsive with these tubes!

                      from Va Beach

                      Comments about Electro-Harmonix EL84 Matched Power Tubes:

                      Right now I'll give em a 10 along with GT-ECC83 also installed..I have a Orange Dual Terror with 2-Orange 1 x 12 cabs ,0ne closed and one open.The DT I've had a couple of months and it sounds good .The more i play it the more I think something is not quite there.So I decided to replace all 8 tubes.OH MY GOD.What a HUGE difference in this amp ,it was like a whole new amp.When I opened up the DT the origional tubes that were in it had China printed on the ECC83 tubes and nothing stamped on the EL84's.So I'm thinking low cost tubes come from the factory .The new tubes not only sound awesome but pots on my LP DC Special react and respond like theres no tomorrow.I would recommend these tubes highly
                      These tubes just have sooo much presence its unbelievable.
                      Just installed so I'll give em some time
                      They bring out all you got on my amp aand guitars

                      Electro-Harmonix EL84 Medium

                      By William Dutzek

                      from Nashville, TN

                      Comments about Electro-Harmonix EL84 Matched Power Tubes:

                      I am anxious to purchase their 12ax7 as my preamp tube. If it's as good as their EL84, I may retube my Mesa Boogie DC3 with all EXH. That beast uses a total of 11 tubes.
                      Purchased for my older Bad Cat Mini Cat. The Mini Cat is a single ended 5w amp with a 10" WGS speaker (Upgrade) that uses (1) 12ax7 preamp tube and (1) EL84 power tube. I have tried other major brands but the Electro-Harmonix is by far my favorite! Great low volume bass response. Real clarity in the mids and highs: You can hear yourself picking and strumming. The Bad Cat has a whole lotta guts for a 5 watter: The EHX holds tough when the Mini Cat is cranked and brings out the best of that amp's pushed bluesy kickin' sound.
                      The EHX feels a little thicker than the Sovtek EL84 and JJEL84: In fact it weighs 20g vs. the Sovtek (18g) and the JJ (14g) according to my digital scale. Don't know if that really matters. It's just an observation. I tried a GT silver series a while back and it started smoking after an hour. It got so hot the label burned off it. Don't know how much that one weighed, but I never tried another GT after that negative experience.
                      The Electro-Harmonix is competetive priced to other brands. Maybe a couple of bucks more. Chump change in the general scheme of things.
