Description
These Sylvania USA made 6SN7 GTB tubes test: 100-104/50 96-96/50 on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 77-77/50 or higher. Tested for shorts, emission, gas and noise. Dated January 1969 and August 1970. They are closely matched and brand new. These are in great shape. See the pictures for condition and ask questions. I do not accept returns unless the items are not as described. I’m in the process of listing thousands of tubes. If you want something in particular message me to see if I have it. Thanks!
