Pair of Tung-Sol 5U4GB tubes that test 60-61/40 & 61-60/40 on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 62-62/40 or higher. These are strong. Tested for shorts, emission and noise.

Dated June and July of 1957. The tubes have some scratching on the base. These are used. 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!
