      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.

        Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

        Purchased a quad set to replace Sovtek 6l6 in a Krank Rev1. Sounds good, not too much on the low end but that is more just the amplifier. Can't say I hear a significant difference between tubes.

          Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

          I have bought many sets of Ruby power tubes, never had any failures. I prefer JJ 6l6 power tubes, but have trouble with their dependability as well as the pins being a little smaller than most 6l6 tubes so they will not fit very well. Never had any of those problems with Ruby.

                      Do your homework and know what sound(Tone) you are chasing. Burn your tubes in. They are the best sounding 6L6 I have heard. Musicians Friend is quick and professional. For the price you can't beat the deal. Know what the typical lifespan of a given tube is for your purpose. I do not perform live and more into recording purposes only.... For now. With that being said they should last a year or so depending on how much I use my Lee Jackson amp

                        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.

                              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.
