This is a perfectly balanced single Siemens 12AT7/ECC81 made in Munich, Germany. This tube tests strong, and both plates test identical to each other. This tube has short, ribbed gray plates shaped like wings, white lettering, and a halo top getter. These are highly sought after Siemens 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:
5,200/5,200
