Why Buy From Us?: Why should you purchase your tubes from Lakeland Music? We utilize a unique testing process, using a combination of vintage tube testers for shorts and gas checks, and precise modern testing equipment that is both expensive and time consuming to fully verify the meaningful electrical values of every tube we list. We also audio test every tube in one of our many amplifiers, both instrument and hi-fi, for sound quality. Our tubes may be more expensive than some big retailers, but when you work with us you know exactly what you are getting, dispelling the myth that buying tubes from eBay is a gamble, or that there is “only junk on eBay”. We’ve seen this opinion on hobbyist forums for many years, and took it to heart. We want to be the exception to this viewpoint. You are bidding on Philips ECG 12AT7WC JAN NOS Vacuum Tube (5 Tubes Total Available For Sale 1 Tube Per Bid) Made in USA, black plates, large halo getter, 1981 date codes. Please note this is a multiple item listing, green labeling on glass will have varying presentation between tubes. This has no bearing on tube function or data points, it just means the tube you receive may not have identical labeling to the tube in the photos. U.S. Air Force JAN “WC” version, these are one of the best 12AT7 ever made, and have been documented to be some of the only tubes that last in amps that tended to burn up 12AT7 tubes very fast. We use these in the phase inverter stage of all of our high gain and medium gain amps, which gives more clean headroom and less power amp distortion. This allows you to drive the preamp section harder, with more clarity and smoother harmonic content. They can also be used in the Reverb stages of amps with spring reverb, which really dials back the over bearing “springiness”, and gives you wider control over the total amount of Reverb. They are used in so many applications: – Phase Inverter stage on almost any amplifier, especially high gain amps. – Reverb stage on vintage amps that use a 12AX7. (Reduces overwhelming reverb). – Any normal 12AT7 stage, where you want the best possible quality tube.

Note to customer: Returns: We provide a 30 day return policy for our items, as long as they are in 100% the same condition as when we listed it.

Please keep any boxes, pins or labeling intact. If an item is returned altered, damaged, or different from how we listed it, we may charge a restocking fee depending on the condition of the returned product. Test Results: First, we test all of our tubes, in both a calibrated tube tester, and perform a live audio test in guitar, hifi and vocal amplifiers. Our testing practices are stringent, and have given us well over a decade of satisfied clients. Still we cannot guarantee exact test result numbers or data, nor can we foresee the results you will have using our parts in your equipment. Our recommendation is to contact us before purchasing so we can do our best to help you find a good match for your needs. We do not offer partial refunds or returns based on test data or test numbers. NOS Tubes: “NOS” is a search term many buyers use on eBay to search for vintage tubes. This is a widely criticized word that many electronics experts and hobbyists enthusiasts do not like to hear unless the item is brand new, sealed in the box. When it comes to listing as a seller, sometimes to match your product with a buyer who may be looking for your item, but doesn’t always know the proper terms to search, you must use the terminology most used by the buyer for the product they are looking for. Many tube buyers only know vintage tubes by the term “NOS” and will not type “vintage” when searching for what they are looking for. Therefore, when we list “NOS” in the title, we are only describing a vintage tube. When a tube is new in box, we will combine that with the term “NIB”, or “New In Box”. We will also list that the item is “NIB”, “NOS”, or “new in box”, when a vintage item meets a certain threshold of visual quality combined with test data for it’s age and type. This still may show signs of handling, marks, dirt, dust, rust, patina,or tarnish. This is normal for items stored for many decades in sometimes less than ideal climates. These items also have been understandably handled and changed hands many times over their life. This usually results in less than perfect cosmetic condition, but by no means indicates the item is used. Most audio experts are in 100% agreement on this. We hope this clears up the title term NOS for some buyers who have or will inquire about this. We are not trying to misrepresent our items, we are simply attempting to put our listings into the hands of those who want to see them. Performance Of Vintage Items: We cannot guarantee a vintage item will perform the same with or in your equipment as it did in ours, or that a vintage item will continue to function once it is used. We list our items honestly and accurately as possible, many times the items we are selling are 50-80 years old. ****BUYERS PLEASE NOTE THAT IF YOU WISH TO PURCHASE VACUUM TUBES OUTSIDE OF THE U.S., PLEASE CONTACT US BEFORE PURCHASING AS WE MAY NEED TO REMOVE THE GLOBAL SHIPPING PROGRAM OPTION FOR YOU. WE STILL SELL TO OUR INTERNATIONAL CUSTOMERS AND APPRECIATE YOUR BUSINESS!**** **Buyer agrees by bidding there are no returns for international sales In the near future, will will be moving our store permanently to Reverb, the best music gear related marketplace. This is due to many reasons, most significantly eBay’s new Managed Payments requirement, and the abandoning of Paypal as an option for sellers. Find our store, Lakeland Music on Reverb if you can’t find it here. Thank you to all of our loyal clients!
