Philips JAN 5814A Perfectly Matched And Balanced Pair NOS 12AU7 5814

This is a perfectly matched pair of JAN Philips 5814A tubes that were made in the USA. These tubes were manufactured to rigorous military specifications and you can expect low noise and great performance. Each of these tubes tests identical to the other, and both are visually almost identical, and they both test at the top of the range. They have date codes from 1985. These tubes have long gray plates, green lettering, and a halo top getter. These are highly sought after Philips 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:

3,000/3,000
3,000/3,000
