Pair of Early 1950’s BRIMAR 6SL7GT Vacuum Tubes D Getters Closely Matched CV1985
These BRIMAR made 6SL7 tubes test: 46-48/32 48-44/32 on my TV-7D tester (calibrated annually). Brand new tubes should test 49-49/32 or higher. Tested for shorts, emission, gas and noise. They are closely matched and in great shape. They are used and test strong. One tube is slightly taller than the other (physically). 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!
