Excellent Pair of Vintage Raytheon 6SN7WGT. Great tubes in one. Military spec JAN CRP. Test results on my calibrated TV7 tester for tube 1 are 94 & 96 and test results for tube 2 are 92 & 88 with the minimum (65%) being 50. One tube is a little shorter than the other. Listening tested in amp for excessive noise and microphonics. Listened to the pair in our 300B amplifier; They are dead quiet when the amps are muted and sound wonderful when played. All tubes are guaranteed to test good when they arrive. Therefore for the next year I will list 100s of antique radios, audio tubes, tube amplifiers, radio parts, and radio tubes, so bookmark my username stonevintageradio and check in each week.
