This is a well matched pair of Amperex 7119 tubes. These tubes were made in the USA by Amperex. Each one of these tubes tests very closely to the other. These tubes are visually very similar.  These tubes were manufactured to rigorous standards so you can expect low noise and microphonics. These tubes have long gray plates, orange lettering, and a halo top getter. These are highly sought after Amperex 7119 / E182CC 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:

14,375/14,000
14,000/14,500
