You are bidding for one pair Sylvania 6SN7GT 6SN7 same codes Black Plate Bottom Foil Getter matched pair. The tubes were tested strong on TV-7. These tubes were made for the US military so they are deadly quiet, clear, detailed and dynamic. They were all tested on my amplifier and worked marvelously. I found them (without boxes) on the attic from my grandfather’s collection which look almost unused and in mint condition. Happy bidding. Thanks

P/S: The shipping fees in the listing is by regular mail (normally Vietnam post or SG link) taking from 12-25 days depending on buyers' local customs. To some regions, it can take even longer than that. Besides, Vietnam post is not always available to some countries in South America, Northern Europe or Africa. Please ask me before paying. If you want to use express shipping services like DHL, Fedex or UPS express taking 3-7 working days, you have to pay an extra of around $68.75. (For order over $1000, Express shipping service is a must. Please wait for the invoice to pay). Please let me know so that I can send you an invoice. If the item(s) purchased may not arrive or faulty, please don't hesitate to contact me before opening cases on ebay. I am willing to reach to a solution and make you completely satisfied. Thanks a millionk
