This is a well matched pair of Sylvania 12AU7 tubes that were made in the USA by Sylvania. The tubes were manufactured to rigorous industrial standards, so you can expect low noise and microphonics. One of the tubes is almost perfectly balanced. Each of these tubes tests closely to the other, and both are visually almost identical. These tubes have long black plates, faded or yellow lettering, and square top getters. These are highly sought after Sylvania 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:
2,300/2,200
2,100/2,325
