You are bidding for one pair Western Electric VT-25 10Y 210 black plates ceramic base foil Getter NOS Matched Tested Excellent On TV-7 at 90-94/38 min good (58-60=100%). These tubes were made for military purposes so they are deadly quiet, clear, detailed and dynamic. These were tested on my amplifier and all worked marvelously. I found them on the attic from my grandfather’s collection which look almost unused and in mint condition. These tubes are super rare and sought-after which are even rarer than single/mono plate version. Happy bidding. Thanks

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