This is a nicely balanced single GE JAN 12AT7WA vacuum tubes. It was made by GE in Canada. These military spec tubes are an excellent upgrade to standard 12AT7. The heavy duty construction helps minimize microphonics. Both plates are closely balanced. This tube has short, ribbed gray plates shaped like wings, red lettering, and a D-horseshoe top getter. These are highly sought after GE JAN 12AT7WA 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:
4,400/5,000
