GE JAN 5814A △ Delta / Triangle, Gray Plate Perfectly Balanced Single NOS 12AU7 5814 12AU7A

This is a perfectly balanced single GE JAN 5814A tube that was made in the USA. It has the coveted "Delta" triangle that signifies high quality. This tube was manufactured to rigorous military specifications and you can expect low noise and great performance. Both of the plates test identical to each other, the tube is perfectly balanced. This tube has short gray plates, green lettering, and a top halo getter. These are highly sought after GE 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:

2,850/2,850
