This RCA UX-171-A tube tests 79/42

on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 65/42 or higher. Tested for shorts, emission, gas and noise.

This tests very strong but I would bet it is used. It has a scratch on the top of the glass shown in the last pictures. 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!
