You are bidding for one pair Sylvania 6SN7W Short Bottle Fat Base Black Plate Chrome Top Matched Pair carefully tested on my TV-7 as shown in photos and sound wonderful in my hifi system. On my TV-7D/U, min good is 50 (65%) and max is 78-80 (100%). These tubes are short bottle version made for US navy (much superior than ordinary ones). There are many in stock so I’ll choose the best matched for you. Also, the letterings may be a little bit different but they are exactly the same type with JAN CHS and navy anchors as shown. If you need photos, please request before I send the tubes out to you. 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 $60. Please let me know so that I can send you an invoice. If the item(s) purchased may not arrive or be faulty, please don't hesitate to contact me before opening cases on Ebay. I am more than willing to reach to a solution and make you completely satisfied. Thanks a million
