Tung-Sol 12BH7A Black Plate Halo Getter Matched (4.9%) Pair NOS 12BH7 ECC99

This is a matched and balanced pair of Tung-Sol 12BH7A tubes that were made in the USA and they have Tung-Sol markings on both tubes. They are visually very similar. 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. They have black plates, white or faded lettering, and a halo top getter. These are highly sought after Tung-Sol 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:

2,425/2,550

2,500/2,500
