And now for the fine print:

This is a no returns listing. Photos are part of the item description. Tubes were tested for mutual-transconductance, shorts, noise, and gas on my calibrated Hickok 532 tester. Your specific test results may vary based on the tester and test conditions. Test results may not completely represent how the tube will function under working voltages, and I cannot assure you the tube will meet your subjective sound preferences. Scrutinize the photos and the written description and ask any questions before you bid. Just know that once you've won the tubes, they're yours. 

I have switched to a no-returns policy only because, in my experience, there is a small percentage of folks (maybe 15%?) who must enjoying trying out different tubes for a few days and when they're finished playing with them, trying to get a refund claiming they are defective in some way. If you're not one of that 15%, then bid with confidence and trust that you're getting a quality tube that is meticulously and accurately described. I have been a trusted eBay seller for more than 20 years.
