GE JAN 12AT7 Gray Plate Balanced Single NOS ECC81

This is a well balanced single GE JAN 12AT7 vacuum tube. This tube was made in the USA and is an excellent upgrade to current production Chinese and Slovakian junk. It was manufactured to rigorous military standards so you can expect low noise and microphonics. Both plates are very closely balanced. This tube has short, ribbed gray plates, white lettering, and a square top getter. These are highly sought after GE 12AT7 tubes, act quickly before they sell out!! More available upon request.

Be wary of sellers who list tubes that are matched without providing test results or the equipment that they used to test the tubes.

I personally tested these tubes on my recently calibrated Hickok 600a tube tester and the results are as follows:

5,600/4,650
