GE 12AU7 Gray Plate Perfectly Balanced Single NOS ECC82 12AU7A

This is a perfectly balanced single GE 12AU7 vacuum tube. **I have hundreds of pairs and singles of this tube.** These tubes were made in the USA and are an excellent upgrade to current production Chinese and Slvakian junk. This tube has plates that test similar to each other. It was manufactured to rigorous industrial standards, so you can expect low noise and microphonics. This tube has short gray plates, white or red lettering, and a halo or horseshoe top getter. These are highly sought after GE 12AU7 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:

2,900/2,900
