I've been an eBay seller since February of 2000. This is theonly seller account I have on eBay and the pictures you see are ofthe actual tube(s) you’ll receive. Tubesare described, tested, and presented to the best of my ability, subject to the limitations of the equipment that I have available(Hickok 539C and 6000A). Test results are likely to vary between yourequipment and mine due to the imprecise nature of 60-year-oldconsumer-grade test equipment, so take the test results given as anapproximate value.

That obligation ceases if you decide to resell the tube.Alltubes are stamped with an identifier to ensure that, in the event ofa return, I get the tubes back that I originally sold.
