This is a well balanced single Sylvania 12AT7 tube. They were made in the USA by Sylvania. Each one of the triodes tests very closely to the other. It was manufactured to rigorous industrial specifications so you can expect low noise and microphonics. This tube has flat black AX-style plates, faded red lettering, and a halo top getter. These are highly sought after Sylvania 12AT7 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 tested this tube on my recently calibrated Hickok 600a and TV7D/U tube testers.
The results are as follows:
4,400/4,900
