You are bidding for One Pair 6072/12AY7 black plate, triple mica Gold pins NOS made in USA . The tubes are super rare, hard to find and in mint condition. Return is accepted if you pay return shipping fees. All the tubes are carefully tested on my tube tester TV-7 at the NOS range with no short and no gas. Again the price is for one pair although there are two pairs available. Please choose the number you need to buy. 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
