RCA 5965 Gray Plate Triple Mica Well Matched (8.3%) Pair NOS 12AT7 12AV7 5965A

This is a well matched pair of RCA 5965 / 12AT7 / 12AV7 vacuum tubes.  These tubes were hand selected from the best production in the factory.  These tubes have plates that test closely to each other. They were manufactured to rigorous industrial standards,so you can expect low noise and microphonics. These tubes have gray plates, triple micas, red lettering, and top getters. These are highly sought after RCA 5965 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:

12,625/13,125
13,125/12,500
