This is an almost perfectly balanced single Raytheon 12AX7A tube. It was made in the USA by Raytheon. This is the 1960s vintage that has won so many 12AX7 shootouts and contests and has a phenomenal sound. These tubes are well matched and balanced. This tube was manufactured to rigorous specifications for reduced noise and microphonics. This tube has long black plates, yellow lettering, and halo getters. These are highly sought after Raytheon 12AX7 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:


2,300/2,300
