Perfect matched pair of vintage Mullard E188CC audio tubes - Made in Holland - 1964 - Identical Date Code - Very Rare Tube Summary This is not a listing about audio tubes but an invitation to hear the the sweetest voice on Earth. Yes no other tubes can deliver vocals like the Mullards, whether theyre from Blackburn, Mitcham, or Heerlen, and thats a fact. The Mullard labeled and Holland made E188CC tubes are extremely hard to find today and are being hunted to extinction by audiophiles and sound professionals. Sound Characteristics Be assured - you will not miss one single bit of the legendary Heerlen sound just because the tubes are labeled Mullard. The proud delta symbol in the date code tells you this is 100% textbook natural sound from Heerlen: warm and lively tone with infinitely expansive midrange and nice extension on both top and low ends. The technical advantages of the E188CC/7308 design on these tubes have taken that sound to the next level: you get more forward vocals and a wonderful airy top end, super large images and incredibly spacious sound stage. Like any other E188CC/7308 tubes, they have low noise to the vanishing point, and that makes these tubes also one of the go-to tubes for details & clarity. Appearance & cosmetic condition We treasure this pair also because of the pristine condition of both tubes (clear inscription and clear date codes), which is amazing given the tubes age. What makes this pair even more rare is the identical date code on both tubes: delta 4C1 (delta = Heerlen, 4 = 1964, C = March, 1 = 1st week of the month) Professional testing & sound evaluation Both tubes tested Strong NOS (100% - 110%+ mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 14,500/13,700 Tube 2: 13,500/13,500 Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound so the higher the numbers the better. The pair worked wonderfully & sounded terrific in our test amp (Liquid Platinum by Alex Cavalli.) during professional sound evaluation. Shipping - Customers outside the US please pay attention Same business day handling. Combined shipping available multiple purchases. Ship worldwide! Flat-rate shipping within the US. International shipping is through eBay International Shipping program by default. Its the least expensive option and customs declaration is automated but it may take longer than other carriers. If you prefer to use a different carrier please contact me before you make payment so I can get you the correct shipping rates ahead of time. Return Policy - Please READ carefully First of all, returns are acceptable. All the tubes I list for sale are guaranteed to work because we run professional tests and listening sessions on them before packing. However, given that sound quality is an extremely subjective thing and its also not uncommon to run into combability issues because of different amp designs, please work with me before submitting a return request through eBay or opening a item defective or not working case. I would really appreciate it. I do my best to make you happy with your purchase but please respect the professional work (matching & testing tubes and evaluating sound) I have done to make these wonderful vintage items available to you at a reasonable price. Secondly, if you are a tube roller looking to game the return system, Number One STOP. I am a professional audiophile for over two decades and I advise orchestras and music studios in sound production so I do know what I am talking about when it comes to sound and equipment - tubes, headphones, DACs, amps - you name it. So no tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats also guaranteed.

Perfect matched & balanced pair of vintage Amperex USN-CEP 7308 audio tubes w/ Gold Pins - Made in USA (1963/64) - Strong NOS - Very Rare Tube Overview Built and tested according to military specs of the US Navy, Amperex USN-CEP 7308 has been rated one of the most reliable 7308/E188CC tubes known to the world: its quality is more than premium, although it doesnt carry the aweing PQ label like its more expensive siblings do; its performance is superb and in fact very few tubes in this price range can claim to be stronger; its low noise should only by judged by the most experienced sound experts because we are talking about the very tube built for and certified by the US Navy for mission-critical communication devices; its sound signature is phenomenal (I dont use this word very often to describe tube sound) and many audiophiles consider the Holy Grail (75 Reflektor 6N23P) the only possible upgrade path to go from here. Sound Qualities The clarity and sound detail on USN-CEP 7308s are second to none. These tubes deliver the same resolution and grip you get from the best German and Dutch tubes from the same league(7308/E188CC.) These tubes have a clean, incisive presentation, but are also euphonic and musical. Like the HGs they put all the differing and competing attributes together in one excellent package. As a result, theres no one area they are weak in so you can use them for most listening occasions - music, monitoring or movie watching. The sound stage is not only wide but also deep so every listening experience feels like at a live concert. The instrument separation is not done as beautifully anywhere else, as one would expect from tubes this quiet. The top end is smooth and airy and theres absolutely no brightness or harshness. The midrange presentation is very similar to the Amperex Holland 7308/E188CC tubes - large, expansive and transparent - with added thickness in the upper midrange, which makes your sound warm and intimate, especially on the vocals. The bass delivery is world-class, as one should expect from a military tube at this level of the game: accurate, full-bodied, dynamic and always present. Appearance & cosmetic condition This pair is so rare because about 95% of the inscription (Amperex brand, Made in USA print and PQ logo) is intact and perfectly visible, which is amazing given the age of these tubes. The two tubes have the exactly same control code VR5 and date codes very close to each other: *3J (* = Amperex New York, 3 = 1963, J = Oct), *4B (* = Amperex New York, 4 = 1964, B = Feb) meaning they were manufactured with less than four months apart although in two different years. Professional testing & sound evaluation Both tubes tested Extremely Strong NOS (120%+ GM) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 15,000/15,100 Tube 2: 15,100/15,500 Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound, so the higher the numbers the better.

Perfect matched & balanced pair of vintage Amperex JAN 7308 audio tubes w/ Gold Pins - Made in USA (1966) - Strong NOS - Very Rare Tube Overview Built and tested according to military specs of the Joint Army Navy (JAN), Amperex JAN 7308 has been one of the most reliable 7308/E188CC tubes known to the world: its quality is more than premium, although it doesnt carry the aweing PQ label like its more expensive siblings do; its performance is superb and in fact very few tubes in this price range can claim to be stronger; its low noise should only by judged by the most experienced sound experts because we are talking about the very tube built for and certified by the US military for mission-critical communication devices; its sound signature is phenomenal (I dont use this word very often to describe tube sound) and many audiophiles consider the Holy Grail (75 Reflektor 6N23P) its only possible upgrade path. Sound Qualities The clarity and sound detail on JAN 7308s are second to none. These tubes deliver the same resolution and grip you get from the best German and Dutch tubes from the same league(7308/E188CC.) These tubes have a clean, incisive presentation, but are also euphonic and musical. Like the HGs they put all the differing and competing attributes together in one excellent package. As a result, theres no one area they are weak in so you can use them for most listening occasions - music, monitoring or movie watching. The sound stage is not only wide but also deep so every listening experience feels like at a live concert. The instrument separation is not done as beautifully anywhere else, as one would expect from tubes this quiet. The top end is smooth and airy and theres absolutely no brightness or harshness. The midrange presentation is very similar to the Amperex Holland 7308/E188CC tubes - large, expansive and transparent - with added thickness in the upper midrange, which makes your sound warm and intimate, especially on the vocals. The bass delivery is world-class, as one should expect from a JAN tube at this level of the game: accurate, full-bodied, dynamic and always present. Appearance & cosmetic condition This pair is so rare because about 95% of the inscription (Amperex brand, Made in USA print and PQ logo) is intact and perfectly visible, which is amazing given the age of these tubes. The two tubes have the exactly same control code VR5 and date codes very close to each other: *6H (* = Amperex New York, 6 = 1966, H = August) , *6K (* = Amperex New York, 6 = 1966, K = November) meaning they were manufactured with only four months apart although in two different years. Professional testing & sound evaluation Both tubes tested Strong NOS (100% - 120% GM) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,700/13,200 Tube 2: 14,800/14,200 Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound, so the higher the numbers the better. The pair worked wonderfully & sounded terrific in our test amp (Liquid Platinum by Alex Cavalli) during professional sound evaluation. Shipping - Customers outside the US please pay attention Same business day handling. Combined shipping available multiple purchases. Ship worldwide! Flat-rate shipping within the US. International shipping is through eBay International Shipping program by default. Its the least expensive option and customs declaration is automated but it may take longer than other carriers.

Return Policy - Please READ carefully First of all, returns are acceptable. All the tubes I list for sale are guaranteed to work because we run professional tests and listening sessions on them before packing. However, given that sound quality is an extremely subjective thing and its also not uncommon to run into combability issues because of different amp designs, please work with me before submitting a return request through eBay or opening a item defective or not working case. I would really appreciate it. I do my best to make you happy with your purchase but please respect the professional work (matching & testing tubes and evaluating sound) I have done to make these wonderful vintage items available to you at a reasonable price. Secondly, if you are a tube roller looking to game the return system, Number One STOP. I am a professional audiophile for over two decades and I advise orchestras and music studios in sound production so I do know what I am talking about when it comes to sound and equipment - tubes, headphones, DACs, amps - you name it. So no tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats also guaranteed.
