Tung-Sol 12AU7A Gray Plate Well Matched (7.3%) Pair NOS 12AU7 ECC82

This is a pair of Tung-Sol 12AU7A tubes. These tubes were manufactured in the USA by Tung-Sol. They test very close to each other, and stronger than NOS. These tubes have been manufactured to meet the highest industrial standards, so you can expect low noise and microphonics. Both of these tubes have long gray plates, white lettering, and top halo or horseshoe getters. These are excellent Tung-Sol 12AU7A 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:

2,375/2,200
2,350/2,225
