Item is one unmatched lot of GE 5814A vacuum tubes. These tubes are used and have dust, shadowing or label discoloration that appear with extended use. However, they are clean and test strongly and will perform well for a long time. These tubes and have been tested and are good. All tested tubes are at least GOOD on my Superior Instrument tube tester (most 7, 8 or 9 pin tubes) or meet the minimum strength on my U-Test-Em drug store tester (most other tubes). If a tube is labelled as untested, it is because I do not have the necesssary equipment to test it. All tubes that dont meet your expectations can be returned regardless of their test status. Sets of vacuum tubes labelled as pairs, quartets, sets, etc, came to me grouped together or labelled as such. My tube testers are not sophisticated enough to guarantee that all sets of tubes are fully matched correctly. Again, if you are unsatisfied with the tubes you receive, you can send them back for a refund. --> All items are inspected to ensure that they ship in working order ready to use. Any damage or wear outside of that which comes from normal usage is noted above in the description. Photos are of the actual item for sale, or if more than one is available, representative of any of them. Save on Shipping!!! Single items ship to anywhere in the USA at the shipping price listed.
