You are bidding for One Pair Telefunken E180F 6688 Gold pin Tested NOS Matched made in Germany. The tubes are super rare, hard to find and in good condition. They were tested on my AVO CT160 over 100%. Return is accepted if you pay return shipping fees. All the tubes are carefully tested on my tube tester TV-7

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
