This is a well balanced pair of RCA 5963 tubes that were made in the USA. They test very closely to each other and are visually very similar. These tubes have plates that test similar to each other. These tubes were manufactured to rigorous specifications and you can expect low noise and great performance. They have long black plates, white lettering, and a D top getter. These are highly sought after RCA 5963 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 hand tested these tubes on my recently calibrated Hickok 600a and TV7D/U tube testers.

The test results are as follows:


2,925/2,900

2,900/2,950
