You are bidding for one Pair Mullard ECC82 12au7 Box Plate Square Getter NOS Testing Values Matched NOS NIB tightly matched. Both are tested NOS, balanced on my TV-7/U and sound wonderful in my hifi system. These are super rare and sought-after items. They are first version with winkle glass. The sound quality is rated as Genalex or GEC versions during the 1950s-1960s. Stunning tubes I must say. What you see is what you get. Return is accepted if you pay your return shipping fees. Sold as is. 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
