Up for grabs from a large personal collection of vintage NOS (New Old Stock) Groove Tubes are some highly desireable (and many say the best ever) Groove Tubes 6L6 Old Style Quartet that were originally manufactured for GT by General Electric back in the early to mid 80's right in the USA. These are still packed in their old original GT style 2" clear plastic sleeves (although I will repack them better for shipping). These original Groove Tube Quartets were matched and packed about 25 years ago when GE was still in operation and supplying companies like Fender and Groove Tubes with Made in USA power tubes. BTW, these are also the EXACT tube design GT later reissued after buying the original GE 6L6 tooling, processing methods, materials and actual production machines. Considered by many guitar players and Hi Fi Golden ears to be the VERY best US made 6L6 Tetrodes of all time. And like all USA made vintage NOS tubes you can expect triple the lifespan that Russian, Slovakian or Chinese made tubes give today...they will very likely out last YOU!I think GE made the best sounding USA 6L6, closely followed by the RCA and then Sylvania (later aka ECG Phillips). But most players and HI FI buffs agree these 3 are at least on equal terms with each other. All good, each w/ it's own sonic signature and minor technical advantages. Frankly it's really hard to pick a favorite (so I used and loved them all!). No offense, but nothing made today from Russia, Slovakia or China comes even close to sounding and performing like these clear top beauties, with perhaps the single exception of the still currently in production Groove Tubes 6L6GE reissue which are 99% close copies made from some USA materials but assembled in the Shuguang factory in China for GT under contract...these come close, but nothing is like the original article. Use these to REALLY upgrade your sound; get that TRUE vintage USA tube tone for your Fender, Boogie, Ampeg, Peavey, or Marshall guitar amps, or that correct and original highest quality USA tube performance from your McIntosh, Marantz, Leek, Quad, Audio research or Conrad Johnson HI Fi Amps. This is a NO RESERVE auction with a low starting bid set well under the (per tube) prices I haveseen recently for USED GE 6L6 tubes with auction copy that states "test strong" selling for $50 each...or really clean USED Quad sets for $400+!!But let's face it, new is NEW and used is USED, even moreso w/ vacuum tubes that can test strong and sound like crap and/or be noisy. Think about it; used guitar strings ALSO "test strong", but are worthless if you want great tone...so furgetaboutit with these used "test strong" tubes...they will typically rattle, be highly microphonic, lack bass or highs and have no tone at all...WHICH IS WHY SOMEBODY PULLED THEM OUT TO BE REPLACED WITH NEW TUBES A LONG TIME AGO AND THE YAHOOS SELLING THESE WORN OUT TUBES IN THEIR FANCY HI FI AUCTIONS HAVE NO CLUE HOW TO EVALUATE TUBES...SO DON'T WASTE YOUR MONEY...BUT NOS WHEN EVER YOU CAN AND BE HAPPY!! Remember NEW examples of real USA tubes have exceptionally LONG life cycles that will likely out live you or your amp. This is a unique opportunity indeed, and when my small remaining quantity of these gems are gone t will be no more!FYI, I am selling off a part of my personal collection of various vintage and desirable audio tubes, like these listed , that should be interesting to Guitar players, amp builders and classic Hi Fi enthusiasts. All tubes I sell are 100% guaranteed to meet or exceed factory specifications, no duds. Thanks for looking! Auction notes: I ship tubes anyw in the USA via USPS well packed in a flat rate box service and all my shipments include INSURANCE and SIGNATURE confirmation...which adds some costs but IMHO is safer for all concerned. Also, I am experienced in packing tubes so we can BOTH be sure they will arrive in perfect working condition with no broken glass! Additional costs for International shipping will be born by winning bidder and quoted upon re... read more
