You are bidding for One pair Siemens E288CC Gold pins NOS NIB letterings is a little worn off made in Germany. The tubes are super rare, hard to find and in mint condition. Return is accepted if you pay return shipping fees. All the tubes are carefully tested on my tube tester TV-7 at the NOS range. I'll choose a tightly matched pair, matched quad for you because there are plenty in stock. Please ask me any question before bidding. 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.
