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.

Package arrived in less than 100% condition. One tube in quartet was very much "hotter." The hot tube wasn't marked the clearest. When it worked after biasing, it sounded great in my Peavey ValveKing Mkii 100w Head. Maybe wasn't biased correctly due to my own idiocy, but didn't seem to like long periods of play. But wasn't pleased, with much.

    Noticeable positive difference in headroom and warmth of tone to my 5150 ll as opposed to the sovtek's and jj's I have used in the past.

      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.

        Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

        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!!

            Can't beat this price with a big stick and both hands! I couldn't have asked for better!! Great price, quick delivery. I am now a lifelong MF customer!
            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!

              Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

              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.

                    The tubes are fine. Paid for ex shipping and the boneheads sent them ground. They showed up 5 days after I needed them. Good tubes but nothing will I purchase again from MF.
