This is a matched pair of RCA 6EU7 tubes. They were made in the USA by RCA and one is branded for Wurlitzer. They are visually almost identical, and they both test better than NOS. These tubes were manufactured to rigorous industrial specifications so you can expect low noise and microphonics. These tubes have plates that test closely to each other. These tubes have short gray plates, red lettering, and a halo top getter. These are highly sought after RCA 6EU7 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:
2,075/2,350
2,125/2,325
