Pair of Amperex 12AX7/ECC83 tubes that test:

48-44/32

48-50/32

on my TV-7D tester (calibrated 1/27/24). Brand new tubes should test at least 49-49/32 or higher. These are very strong. Tested for shorts, emission and noise.

The tubes have the close date code Delta 3F1 and Delta 4F1. They have O getters. These are lightly used. The one on the left was wrapped in cardboard and the markings are pristine. The one on the right is dusty but I don’t want to clean it to preserve the original branding. See the pictures for cosmetic 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!
