GE Made For HP 12AT7 Gray Plate Balanced Single NOS ECC81

This is a nicely balanced single GE 12AT7 vacuum tube. This tube was made in the USA by GE, branded Hewlett Packard, and is an excellent upgrade to current production Chinese and Slovakian junk. It was manufactured to rigorous industrial standards so you can expect low noise and microphonics. Both plates are 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:

4,450/5,700
