These are well matched Sylvania 5963 / 12AU7 tubes that were made in the USA by Sylvania for the US military. These tubes were manufactured to rigorous military standards, so you can expect low noise and microphonics. Each of the tubes tests closely to the other. These tubes have long gray plates, green lettering, and a halo top getter. These are highly sought after Sylvania 5963 / 12AU7 tubes, act quickly before they sell out!! More available upon request.
Be careful buying tubes from other sellers who list "matched pairs" but do not provide test results or specify the equipment that they use to test their tubes.
I personally hand tested these tubes on my recently calibrated Hickok 600a and TV7D/U tube testers.
The test results are as follows:
2,825/2,725
2,800/2,725
