You are bidding for 4 tubes AEG/RFT EL34/6CA7 Ogetter, tested NOS Matched Quad made in Germany. These tubes are carefully tested on my TV-7/U at 48-48-48-47/30 min good. They are all tested on my Avo CT160 with the reading around 65/75 (100%). They sound wonderful in my hifi system. Super rare and hard to find now. What you see is what you get. 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
