This is a closely matched pair of RCA 6201 / 12AT7 vacuum tubes. These industrial spec tubes were made by RCA and are an excellent upgrade to normal 12AT7 tubes. The heavy duty construction helps minimize microphonics. Both tubes are very closely balanced. These tubes have short, ribbed black plates, red lettering, and triple micas with extra support rods. These are highly sought after RCA 6201/12AT7 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:
5,000/4,800
4,800/4,900
