Sylvania JAN 5814A Triple Mica Gray Plate Well Matched (7.5%) Pair NOS ECC82 12AU7 12AU7A 5814

This is a well matched pair of Sylvania JAN 5814A tubes that were made in the USA. Each of these tubes tests closely to the other, and both are visually fairly similar. These tubes were manufactured to rigorous military specifications and you can expect low noise and great performance. These tubes have short gray plates, green lettering, triple mica, and a halo top getter. These are highly sought after Sylvania JAN 5814A 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:

2,775/3,000
2,850/2,975
