This listing is for date matched pair of 12AT7 vacuum tubes. Both were tested on my TV-7D tester calibrated Jan 27, 2024.

Minimum good value for 12AT7 is 50.

100% strength is considered 77 or higher.

These test matched at 72-78/50, & 72-78/50

They are used and show light signs of it. The date code KX, June 1958, is very visible on one and hard to make out but visible on the other.

I’m in the process of listing thousands of tubes. If there is something particular you’re looking for let me know. Please ask questions before bidding. I do not accept returns unless items are not as described.
