You are bidding for One Pair Telefunken 6SN7 6SN7GTA 33S30B Slightly Used Tightly Matched Pair Tested NOS on my TV-7D/U at 84-84 and 83-84/50 min good (NOS 78-80) as in the photos. The tubes were quite rare, made in Germany. They are in excellent condition. I tested them on my system and they sound awsome. I don’t guarantee testing values on other tube tested except for TV-7 and not responsible for their performance on you amplifier. Return is accepted if you pay return shipping fees. So please ask me any question if you are unsure. I pack the tubes safely and carefully with wrapping paper and foams. However, I am not responsible for any damages during shipment. Local pick up or do-it-yourself shipping is welcome. What you see is what you get. Thanks

P/S: The shipping fees in the listing is by regular mail (normally Vietnam post) 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 million
