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.

        Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

        I've been using these as service replacements mostly because they're Shuguang made and usually reliable. However I have had several early failures, one in my own Showman as I was watching it in about ten minutes, a couple bad out of the box, and one that caused me considerable rework which I had to eat the cost of. That being said I hope the troubles are over because when they work they're a nice piece of gear. I've had two amps in recently that make the point. A Peavey 6505 which came with Rubys as original equipment, still testing well and balanced after three years in the field, and a Blackstar Artist 30 in which one died after two months. So a good recommendation with some qualifications.

            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.

              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.
