Let me start this off by saying these tubes in my opinion are amazing. The best 6l6s ive heard and used to date. I tried going back to jj 6l6s and after using these rubys they make the jjs sound dry. The rubys have way more bottom end. The cleans also sound better on the rubys. Not to mention the rubys price is great. They also dissapate heat way better. My jjs got really hot which can cause big problemsas to where the rubys maintaned a hot but consistant temperature and it didnt get too hot. Hands down i wouldnt go with any other set of power tubes in my peavey. These are the best.

Got these tubes and put them in my amp. Tried to set the bias and one tube immediately started redplating and drawing a lot of current. Put the old set in and will be returning these. They where a good price ,but if they are not burned in or tested I guess not so much of a deal.Will always buy from a tube dealer who tests and weeds out the bad ones before shipping them out and possibly damaging your amp.

          I bought the Ruby's based on the price and value. Under any other circumstance, I would have preferred to have bought the Mesa tubes but I am a little short on $$$ these days and had to cut a few corners. I have used this product before and it's decent value for the money. Recommend to anyone using a tube amp that uses these kind of tubes and is on a tight budget. Thanks for reading!!

            I have a Peavey Classic 212 VT Series amp and man I love the warm tone that tge ruby tubes put into it. I mainly play SRV a little blackfoot and zz top amd those tubes man they just help me get out the tone and the feelings that i put into those strings. Cause you cant just play music, you gotta feel ot and the sound of the ruby tubes help you feel that vibe.

              Don't know yet about life span, but these sound great in my 1970 Fender Deluxe Reverb. I've used Groove Tube, Electro Harmonix and Sov Tech. The Rubys stack up well against them.

              Ruby Tube 6L6-MSTR tubes. Exact replacement for the factory power tubes that came in my Valveking 100.
              This is my first retube. To the best of my knowledge, it couldn't have gone better!
              Best price I could find on a matched quartet of 6L6 power tubes!!! Imagine my surprise when I realized that they were the exact same as the original power tubes! Purrfect!

                I use these in my Bugera 6260, big improvement over stock. My favorite tubes are JJ 6L6, but the pins are usually just a little too small and do not make a real solid connection in my amps, may just be Bugera's power tube sockets are a little big.

                These are a close 2nd to JJ's for me and for the money: about fifty per Quad.

                        Put one of these and two of Ruby ECC83 (12AX7A) Preamp Tubes in a old Fender champ 12 that has been dead for about 3 years.
                        Man the sound is incredible. Not really screaming over-driven, but maybe the warmest bluest tones I have ever gotten.
                        Can definitely get raw Roy Buchanan sound with my Tele and also warm Chris Rea with my Stratocaster. I am in love with my Fenders all over again and the acoustics also sound very excellent (crystal clear, even chiming).

                        they were very closely matched from the factory( 2 miliamp diference) at the very begining. replaced the originals in an older spidervalve mk.1. heard alot of apionions on this amp but it always was good on rock and metal. put 2 new rubys in with 2 more mullard 12ax7s in the preamp amd set the bias at 38.5 to 39. it realy made this anp worth keeping!. its pretty decent at the cleans now and the heavey stuff is just amazing with such clarity and no mud. go buy a set, bias them right and youll be smilin to!!
                        they have a good musical sound that was noticible to the sovtec 5881 that was in my amp factory! very detailed and pleasing to the ears.
                        aint had a problem with em yet but its only been 3 months.
                        i'd sure buy em again, excellent price and even sweeter sound. im sure theirs better but isnt there always ! if your lookin at these you dont have a muddy solid state to begin with!

                        These Tubes sound wonderful in my Soldano SLO, there rich without being to much treble, very warm, clear and the Greatest Tone! The 5881's that come with the amp are very "Buzzsaw" but the Ruby 6L6 offer the best overall sound, IMO.

                        When you consider the price you are paying for a matched set of power tubes I think your money is well spent.
                        I put these tubes in my 1980's Peavey Classic VTX, replacing a set of Groove tubes. Since I haven't played a gig in fifteen years I decided to try less expensive tubes. So far I am very happy with this set. I only play for my own enjoyment and these tube sound great in my living room. This set is tite and bright.

                        Purchased matched quad for Peavey Valve King Head and also got the Ruby 12AX7 83S. When I cracked the cover for the valve king, lo and behold, these were the stock power tubes. The preamp tubes had an odd mixture of EH, sovtek and something else, when all the tubes became Ruby, why the sound went from okay to awesum. Good for everything from the cleanest twangyest country, to some B.B. to Cream, to Ozzy, Korn and beyond. For warm, pure tube power, this is the 'it' tube.

                            I have been using these power tubes for several years and keep coming back. They are the most affordable and sound good. JJ's are my favorite sounding 6L6, but they are more expensive and I have had several fail within a few months. So I compromise with price and reliability. I use these in Bugera, B-52, and Acoustic 50 watt tube heads. Not real impressed with how tubes are shipped from MF. Most the time with no type of bubble wrap or paper filler. I have started requesting additional packing when I order any type of tube from them and they actually do it. Very nice, thank you MF.

                                Installed these into my Mesa Boogie Triple Rec and they sound great. I can't say they changed my sound, but rather boosted my existing sound. That being said, these are the same high quality as the Mesa tubes I had in it.

                                      I replaced the el34's in my Peavey JSX. I was hoping to beef up the low end and smooth out the highs. Worked like a champ!
