This is a well matched and balanced pair of GE 12BH7A tubes that were made in the USA and they have GE etchings on both tubes. These tubes have plates that test closely to each other. These tubes were manufactured to rigorous specifications and you can expect low noise and great performance. These tubes have short gray plates, red or white or faded lettering, and a halo top getter. These are highly sought after GE 12BH7A 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 this tube on my recently calibrated Hickok 600a and TV7D/U tube testers.
The test results are as follows:
2,425/2,250
2,450/2,350
