You are bidding for one pair Mullard 5U4G CV575 U52 Thin Base Black Plate Pan Tray Getter Matched Pair super rare, one of the best sounding tubes in the world. It was tested NOS and tightly balanced on my TV-7/U at 59-60 and 60-60/40 and sound wonderful in my hifi system. This tube is super rare and sought-after items. What you see is what you get. Sold as is. Return is accepted within a month (buyer pays the returning fees). Please ask before bidding. 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
