        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!

        Matched tubes not matched. there is a 13ma difference in the plate current on what should have been a matched set. Other than that they are high quality tubes But in a push-pull amp mine are unusable. And yes I know how to bias an amp the tubes were swapped for JJ's and they are matched perfectly.

          Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

          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.

                    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.

                      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!!

                        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.

                                  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).
