Philco Lansdale JAN CBRZ 12AU7 Long Gray Plate, D Getter, Balanced (8.6%) Single NOS 12AU7A ECC82

This is a balanced single Philco JAN 12AU7 tube. This tube was manufactured in the USA by Philco in the legendary Lansdale factory in PA. The plates test very close to each other, and stronger than NOS. This tube was manufactured to meet the highest military standards, so you can expect low noise and microphonics. This tube has long gray plates, D getter, and yellow lettering. These are excellent Philco JAN 12AU7 tubes that are highly sought after, 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 tested these tubes on my recently calibrated Hickok 600a and my TV7D/U tube testers and the results are as follows:

2,900/2,650
