This is a very closely matched pair of GE 6211A / 12AT7 vacuum tubes. These industrial spec tubes were made for IBM and are an excellent upgrade to 12AT7. The heavy duty construction helps minimize microphonics. Both tubes are very closely balanced. These tubes have long, ribbed gray plates, faded, lettering, and dual side getters. These are highly sought after GE 6211A/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:
5,150/5,000
4,900/4,750
