You are bidding for one pair TELEFUNKEN G73-R/ECC802S/12AU7/ECC82 black Coated NOS Plain Box with diamond logo on the bottom. I have some carton boxes with 52 pieces each so please order the number you want. These tubes were made for military purposes so they are deadly quiet, clear, detailed and dynamic. They sound like Telefunken ecc802s so they are suitable for those who are seeking for quick, clean and precise soundings. These are tested carefully on my TV-7 tube tester at the nos range and on my amplifier. They all work fine. The items will be shipped from Hanoi, Vietnam by Vietnam post at 28.65 pounds. It may take from 22-45 days due to Covid. If you need the tubes urgently, please pay an extra to use express services like DHL, FedEx... which costs about 63 pounds taking 3-7 working days depending on your local customs. Please let me know soon. Happy bidding. Thanks

P/S: All the tubes are under one-month guarantee and return is accepted but buyers have to pay the returning fees. Video or photo testing will be sent if requested.
