This is a well balanced single GE 6211 / 12AT7 vacuum tube. These industrial spec tubes were made for IBM and are an excellent upgrade to 12AT7. The heavy duty construction helps minimize microphonics. This tubes is very well balanced. This tube has long, ribbed gray plates, white lettering, and a horseshoe top getter. These are highly sought after GE 6211/12AT7 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:
5,750/6,000
