This auction is for one strong old stock pair of Westinghouse 7591 vacuum tubes branded for HH Scott as shown. These are clean with large getters and have the same 1961 date (139). These were tested on our Triplett 3444A tester with results of 11250 / 32mA and 10500 / 30mA, where 11000 is the expected new result. Tubes are guaranteed for 30 days from the day of receipt. SHIPPING: We combine shipping on multiple items. We have thousands of tube types in stock. Please contact us if you cannot find what you want, so we can list it. Due to too many requests by overseas customers, I have to state in the USA it is illegal to falsify the value on Customs forms, as well as being against eBay rules. Do not buy this item and then ask us to falsify the forms. We always declare the sales price, as required by law. Unlike most casual eBay sellers, we are experts at shipping overseas, and we always use the correct customs commodity codes on shipping forms to minimize duties. Casual sellers often omit the codes, which means Customs officials usually default to a high import duty on those items. If you have asked any seller to falsify the Customs forms in the past, ask yourself this question... Why would you want to buy from a company that demonstrates it is dishonest?
