I'm putting on some lots of made in USA audio tubes that I have obtained and tested. Here are (4) Sylvania made 6922's that I have tested on my Heathkit TT-1 mutual conductance calibrated tube tester . They have full to partial silkscreens. They test: 9200/9200, 11400/9800, 6400/7400(low but works) and 1120 0/10000 . The minimum transconductance reading on this tester for a 6922 tube is 8100. I guarantee these tubes are useable in most circuits and have put the readings on the tube.
