I recommend the seller tubemaze (Not affiliated with him) on ebay. He offers 30 day return policy and his prices are fair. Take that Upscale! (Overpriced and no returns)
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.
