+2 for TCTubes. They have a tremendous testing set up, are thorough about it, and honest. They seem to know the value of the NOS/Vintage tubes they have, but you can count on it when you buy it.
Vacuum Tube Retailer Option
I'm a frequent flyer for tube purchases at Upscale Audio and Tubedepot.
However, I've bought a bunch of tubes from this guy in Ohio. He sells on eBay too. He tests his tubes and I've had no duds or issues.

Thought I'd promote good honest midwestern business folk. His prices are aggressively competitive.
