This listing is for 1 12AY7 vacuum tube tested on my TV-7D tester calibrated Jan 27, 2024.

Minimum good value for 12AY7 is 32.

100% strength is considered 49 or higher.

This tested at 55-56/32 and I am selling it as USED. It is very strong though. It has a D getter and is marked with Canadian Aviation Electronics branding. The etching on the tubes makes me think G.E. actually manufactured them. The original box for the tube is pretty beat up and it says “distributed by” not “made by” so I do think GE made this tube.

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.
