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 run through twin 76 peavey classic vtx amps that were re tolexed and restored, I run a 12ax7 behringer pre amp behind it. But without my 6l6 tubes my amp won't run, and these Ruby tubes are thin but provided the best sound possible for my amp. Like any tube... Reliability is a test of time and once I know then I could comment more. But as for now, they are holding up nicely in the cold climate I live in and sound great. Thin and crisp.

          Comments about Ruby 6L6GCMSTR Matched Amp Tubes:

          After listening to these Ruby 6L6GC M (matched pair) STR (Special Tube Request) in my vintage 1980 Fender Pro Reverb Tube Guitar Combo Amp, I noticed how loud, dynamic, and bassy my amp sounded.
          The excess of bass tended to overpower the treble in this amp. I am lucky to own my own tube tester, an old Hickok Model 600A, so I measured my new Ruby tubes coming up with 4280 and 4380 micromhos.
          My measurements compare favorably (relatively) with the 3150 and 3150 "TC" (transconductance) values printed on the labels affixed to each Ruby tube. Also printed on these labels were 39 and 39 "PC" (plate-current) values, at which the transconductance tube tests were conducted by Ruby. Lastly, there is an tube ID number ("016" and "044") printed on the tube label.
          I'm impressed with the care with which Ruby tests and labels their matched tubes!
          I put my new Ruby tubes back in their boxes for future use as spares. My "reference" tubes that are still working well and sounding great in my 1980 Fender Pro Reverb (ultralinear, 70-watt) amp, are Sylvania 6L6GC USA tubes testing at 4100 and 4185 micromhos transconductance in my Hickok 600A tube tester.

          Thanks for reading!

            These tubes are tested and matched before they are sold, At the promotion price, you can't go wrong.

                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.
