      The Electro-Harmonix 6L6EH Power Tube is modeled after the vintage RCA 6L6GC "blackplate." Features large plate dimensions and improved grid structure for increased power handling capabilities. Also features mica spacers with metal springs to eliminate tube rattle and microphonics. The 6L6EH offers tone and performance superior to any other 6L6 or KT66 type.

      These are Electro-Harmonix 6L6EHs in platinum matched sets. Their platinum matching process consists of a 24-hour tube burn-in period followed by a bias (plate) current measurement in milliamps.

      Not only do the tubes do great but so does Customer Service

          Comments about Electro-Harmonix 6L6 Matched Power Tubes:

          I got these tubes through Customer Service to try to fix an issues with my newly delivered BUGERA 6260 (non Infinium). All of my orders have a difficult and long journey to get to me so, often it is hard to discern the who/what/where of problems, so I'll just leave it at the fact that Musicians Friend CS. bent over backward to try to help me,Thanks and GREAT job !

          These medium rated Groove Tube power tubes from Musicians Friend were replacements for the Original Bugera set. I am involved in genres which don't use heavy distortion or piercing hi-end (Jazz, Blues,Bluegrass, Folk, and Folk-Rock). The original tubes sounded very good, but I needed to be monitoring the EQ constantly, I never would have needed the "bright" switch. These new tubes produce a much more balanced tone allowing the HI's to sound great while still having room on EQ to increase Treble or use the "bright" switch. The Mid's are full without being "tinny", and speak of FAT, the lower mids and low's have gained so much fullness I am in awe of how they sound ! The power tubes were not the complete solution but once I got the Amp fully operational, not only did I realize that the original problem might have been a small blessing in disguise (I might not have found these Groove Tubes) I have decided to order a "backup set" of GT 6L6's from Musicians Friend and to stick "like glue" with that choice. If you need a replacement set of 6L6's or are seeking a rich full and a nice FAT sound, without modding to accommodate an EL series tube I highly recommend the Musicians Friend for their Customer Service and these great matched Grove Tube 6L6's (m) for their sound.

              I will not buy Electroharmonix from Musicians Friend ever again I bought a pair of 6v6s (they dont list EH 6v6s anymore)but I checked them with my Mutual conductance Eico tester and they were way of like 10 percent off from eachother! MF took them back but my question is how do you really know if you getting a good matched set unless you verify?

              Bought used X100 with GTs in, one fell out & broke while jamming. Bought mesa tubes locally after I had these ordered, so I got to compare to both.Electro Harmonics has better crunch at lower gain, power sounds as good as any. May have a little more soak in the clean channel, but sounds great.

                    Electro-Harmonix 6L6's Green

                    By 

                    from Minneapolis, MN

                    Comments about Electro-Harmonix 6L6 Matched Power Tubes:

                    I have been using these EH 6L6's in my vintage Fender Super reverb amps (1965 and 1969)and my newer 1965 reissue super reverb and Hot Rod Deville for about 3 years. They have great tone and really do sound very similar to a NOS RCA 6L6 set! I have several vintage used and NOS RCA 6L6's that I am able to save because of these! They also seem to have longer life than Groove tubes (svetlana, sovtek)and better tone in my opinion. These can hold up to extreme volume punishment. Eat, Sleep, Play repeat

                    Comments about Electro-Harmonix 6L6 Matched Power Tubes:

                    I had a tube burn out in my amp and i was freaking out because it happend 3 days before a gig so i went and talked to my dude at a local music store and he told me that he had been using these for years and that he liked them better than the ruby tubes that i was using. I totally see why he likes these better, because im sold on them as well. My amp had more defanition, clarity, punch, and presence. My band playes in A# and we played after i got the new tubes and that was the first time that i was ever able to hear myself on stage and i got a lot of compliments that people noticed a good difference in my sound and i noticed it. These are awesome sounding tubes.

                    They sound huge!!!

                    Comments about Electro-Harmonix 6L6 Matched Power Tubes:

                    I was on my way to a gig and as I was driving I hit a very sharp speed bump and my amp(fender HRD) fell backwards onto my pedals board and it shattered the tubes. Luckily, a friend pointed out that there was a music store near by. I quickly drove there but when I arrived I couldn't find the tubes I usually use. I saw these tubes and they were about the same in price so I tried them. I arrive at the gig and I stick em' in and start sound check. The amp warms up and is ready to go and I'm not expecting much because these were last minute tubes, but then I played that first chord the angels sang. These tubes have amazing clarity and punch to them. All my band mates couldn't believe how much different it sounded. 5 years later I still use them and don't plan to change anytime soon =).
