This is a lot of six used 6SJ7 vacuum tubes in good working condition. Three are branded RCA and three are branded as GE. They have been tested and each tube is labeled with a metered score from 0 to 100. About testing: The tubes were tested on a consumer-grade tube tester which has been calibrated according to its instructions. After one minute of warmup each tube is tested for shorts, leaks, and for general function, and the function test provides a 0-100 (bad to good) metered score. I record this for each tube. In cases where a tube requires two tests I have used the lower of the two scores. Though this tester has proved accurate and reliable enough for testing tubes I use in my own personal devices, please note that this is not a military or industrial grade tester and the results should be considered approximate.
