You are bidding for One pairMullard 10M ECC83/12AX7 Gold Pins Tested Strong Excellent Sounding tightly matched. The tubes were tested on Avo ct160 with the values as shown. Tube testers are varied so I cannot guarantee on any other tube testers except for AVO series. Sold as is. Return is accepted if buyers pay the returning fees. Please ask me anything if unsure. Again, price is for ONE pair. 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
