This is a well matched pair of RCA 12AT7 tubes. These tubes were manufactured by RCA in the USA. Each one of these tubes tests very closely to the other. These tubes are visually almost identical. These tubes have flat gray plates, red lettering, and a halo top getter. These are highly sought after RCA 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:
4,650/5,000
5,000/4,850
