We ship direct to addresses inside the USA ONLY. Any international sales & shipments are handled strictly via the Global Shipping program with no exceptions when a listing has that shipping option made available. Due to the fragile and sensitive nature of vintage items, tubes and electronics we DO NOT ACCEPT RETURNS due to the myriad of factors including but not limited to the buyers unknown equipment condition, bias settings, misuse or mishandling etc. We will work with any buyer to address an issue such as a rare occurance where an item arrives damaged in shipping. We require any buyer that encounters a problem to notify us within 72 HOURS after delivery of a pending issue. As a potential perspective buyer, please be aware that if you feel you can not adhere to and honor the sales terms of our listings, we kindly and respectfully ask that you DO NOT PURCHASE tubes from us. Unless specifically stated in the listing and commonplace amongst the majority of tube sellers, we do not warranty or make any guarantees related to tube performance, noise, hum or microphonics. As is commonly understood, tube testing results do not necessarily translate between different brands and models of tube testers and the different approach each manufacturer used to achieve their test results. As a result all tubes listed for sale are represented and sold on a AS-IS basis and STRICTLY off the results shown and provided by the test equipment used in the listings. As a buyer, you are purchasing based solely from the test data provided and your comfort in our response ratings. No post transaction added terms or expectations not specifically assured in the listing description will be entertained. All the testers used are some of the most respected models ever produced and are professionally calibrated regularly. Calibrations are checked routinely using “bogie standard” tube sets dedicated for each tester. All the aforementioned factors ensure solid and accurate results for the tubes tested and confidence for the buyer in the vintage tubes being purchased. Therefore please let it be understood that we will not guarantee or compare the results off any other tube testers. Partial refunds or returns will NOT be granted based off claims made from unknown testers and their obviously unknown condition and accuracy. As a courtesy, every tube we sell is cleaned and treated with Deoxit to remove 50+ years of corrosion and grime. We recommend that users clean or Deoxit their tube sockets occasionally for best tube performance
