Prev Stop Play Next
This is a pair of Mullard long plate 12AX7 tubes. One has the square D getter and one has the round getter.They tested at 44/46, and 50/42 with 32 being the minimum allowable on my TV7 tube tester. We test all our tubes on a calibrated TV-7U or Sencore tube testers. Some large transmitting tubes are tested on custom built testers or actual amplifiers. Some audio output tubes are tested with a match maker and I will list the IP current as well as the mutual conductance. All my used tubes have been well tested (sometimes twice). I only sell tubes that test strong and have a good life, I will not sell any marginal tubes. When I sell a lot of tubes I do not always list test results, but I will usually leave the test tag on them, these numbers are for reference only and not in any electrical units. All tubes come with a 10 day money back guarantee that they test good and are use able. They will also be extremely well packed.
