The reasons being in as much as tubes can be technically considered parts for amplifiers and such, the main reason is it’s the only way ebay honors a true no return listing as set by the seller. This has become the only way to prevent a very small number of unsavory buyers from intending to temporarily purchase high value vintage vacuum tubes as a means to be able to audition their sound in their equipment. Then in turn would be able to unfairly abuse the ebay buyer protections as a way of forcing a seller to accept a return/refund scenario up to several weeks after taking delivery. Obviously the aforementioned is not a situation myself and other sellers can endure, particularly when in regards to NOS tubes and their accompanying values. Your understanding for why that has to be done is greatly appreciated. I try to make every effort to give buyers reassurance and confidence in their perspective purchases by showing all my testing and proving the quality of the tubes offered for sale. Please ask any questions or concerns and I will respond promptly. USA SHIPPING ONLY. Please check my other listings for more rare and hard to find tubes that are also available. All items will be very well packed and shipped the next day whenever possible. Although I DO NOT ACCEPT RETURNS because of the sensitive nature and personal tastes associated with vacuum tubes, I will certainly work with any buyer to address any problem that may occur such as a tube that arrives damaged in shipping etc. I require any buyer that encounters a problem to notify me within 72 HOURS after receipt of a pending issue. If as a buyer, you feel you can not adhere to the sales terms of my listings, I kindly and respectfully ask that you do not purchase tubes from me. Unless specifically stated in the listing and commonplace amongst the majority of tube sellers, I do not warranty or make any guarantees related to noise, hum or microphonics. As is commonly known tube testing results do not translate between different brands of 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 strictly off the results shown and provided by the testers used in the listings. All the testers used are some of the most respected models ever produced and are professionally calibrated yearly by the best techs in the business. Calibrations are checked regularly using bogie tube sets dedicated for each tester. All of which 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 I will not guarantee or compare the results off any other testers nor will partial refunds be granted based off claims from unknown testers and their obviously unknown condition and accuracy. As a courtesy, every tube I sell is cleaned and treated with Deoxit to remove 50+ years of corrosion and grime. ***IMPORTANT NOTICE TO OVERSEAS BUYERS MUST READ!!!*** Please Be Aware….All my listings are sold strictly for shipping only in the USA. If you are an overseas buyer that registered the ebay global shipping program depot or other 3rd party shippers address as your formal address registered with ebay to be able to circumvent the USA only shipping policy, be aware that as the seller I WILL NOT be held responsible for any items rerouted overseas. You do so at your own choosing and OWN RISK!! I can only guarantee the packages safe arrival at the USA address listed on your ebay account. I WILL NOT BE RESPONSIBLE for any lost or damaged packages outside of the continental USA borders. For Best Results DEOXIT Your Sockets!! FEEDBACK: I will leave excellent feedback for the buyer once I receive their feedback indicating they have received their item in good condition and are satisfied with the transaction and their buying experience.
