This is a balanced single Raytheon Uniline 12AT7 vacuum tube. This tube was made in the USA and was manufactured to rigorous industrial specifications so you can expect low noise and microphonics. This tube is perfectly balanced. This tube has short, ribbed gray plates, yellow lettering, and a slanted halo top getter. These are highly sought after Raytheon Uniline 12AT7 tubes, act quickly before they sell out!! More available upon request.

Be wary of sellers who list tubes that are matched without providing test results or the equipment that they used to test the tubes.

I personally tested these tubes on my recently calibrated Hickok 600a tube tester and the results are as follows:

4,200/4,200
