See All Electro-Harmonix Power Tubes

      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....

      Installed mine in my Hughes and Kettner Tubemeister. Sounded great for jangly soundeds like John Mayer or Red Hot Chili Peppers but got heavy easily (i bought the soft set) for Metallica, Rush, Alter Bridge. But after a week they lost their zing and checked the lights on the back of my amp giving me their status and it was time to change them. What the heck EH?

          Swapped out the standard 6V6 tube from my VHT Special 6 amp. This tube gives my amp a classic, Fender sound. Love it!

                      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.

                      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!
