You are bidding for one pair NOS NIB telefunken ECC803S with diamond logo gold pins made in Germany in the 1960s. There six pairs available as shown in the photos. The tubes are carefully tested on my calibrated TV-7D/U in the NOS range, tightly balanced. I'll give you testing photos and the exact tube before sending them out. There are several pairs available. Please order the number you want. I am willing to answer any question from 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
