GE / Ken-Rad 12AT7 ***Red Tip*** Gray Plate Balanced Single NOS ECC81

This is a well balanced single GE/Ken-Rad 12AT7 vacuum tube. This laboratory spec tube is an excellent upgrade to 12AT7. The heavy duty construction helps minimize microphonics.  This tube has short, ribbed gray plates shaped like wings, faded 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:

6,000/5,300
