Description

These vintage RCA 5R4GB tubes test: 52-50/40 52-48/40 on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test 62-62/40 or higher. In theory. In practice on a TV-7 this particular tube tests around 50ish new. Tested for shorts, emission, and noise. Both have the same date code 7813, or March of 1978. They have O getters, black plates, and are new in box. The boxes are a bit shelf worn, but still intact. These came in a large lot of NOS/NIB tubes, many of which I have listed separately. I do not accept returns unless the items are not as described. Please look at the pictures and ask me any questions BEFORE buying anything. 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!
