The better independent sellers will provide the tube testing numbers and will perform their tests on quality tube testers.
Buyer beware!!! - My friend just got ripped-off from a guy in California who used pictures of his vast tube collection (mostly NOS) that actually were pictures of tubes from other persons websites. My friend got his 2,000 tubes, but they were all non-audio tubes and complete junk.
