Sylvania JAN 6189 Gray Plate Balanced Single NOS 12AU7 6189

This is a single Sylvania JAN 6189 tube that was made in the USA and has Sylvania markings on the tube. This tube was manufactured to rigorous military specifications and you can expect low noise and great performance. This tube has plates that test closely to each other. This tube has long gray plates, green lettering, and a halo top getter. These are highly sought after Sylvania JAN 6189 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 this tube on my recently calibrated Hickok 600a and TV7D/U tube testers.

The test results are as follows:

2,575/2,300
