RCA 12BY7A Gray Smoked Glass Perfectly Matched Pair NOS 12BV7 12DQ7

This is a perfectly matched pair of RCA 12BY7A tubes. They were made in the USA by RCA. Each one of these tubes tests very closely to the other, and they are visually very similar to each other.  These tubes have gray smoked glass, gray plates, red lettering, and a halo top getter. These are highly sought after RCA 12BY7A 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:

11,150
