This is a well matched pair of Sylvania 12AT7 tubes. Each one of these tubes tests very closely to the other. These tubes are visually almost identical. They were manufactured to rigorous industrial specifications so you can expect low noise and microphonics. These tubes have flat gray wing-style plates, triple micas, faded green lettering, and a square top getter. These are highly sought after Sylvania JAN 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:
3,850/4,200
4,150/3,950
