GE JAN 5814A Triple Mica, Black Plate, Well Matched (4.1%) Pair NOS 12AU7 12AU7A 5814

This is a well matched pair of GE 5814A tubes that were made in the USA. They both are visually very closely matched. These tubes were manufactured to rigorous specifications and you can expect low noise and great performance. These tubes have short black plates, white lettering, triple mica, and a top 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:

3,000/2,875

2,875/3,000
