Perfect matched & balanced pair of vintage Siemens E88CC/6922 Audio Tubes - Munich 1965 - Super Strong NOS - Very Rare Tubes Summary Stronger than time! This is the classic beauty in sound, admired by audiophiles for almost 60 years and will still be our top choice in the next 60 years. Particularly, the early 60s Siemens tone is considered the reference sound for serious classical listeners who need to upgrade the sound quality at phono stage. Sound Characteristics The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens E88CC tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken E88CC tubes, Siemens E88CCs produce a warmer, smoother and more musical sound. To see how these two German titans in vintage tubes rival each other, feel free to see our full sound review of 60s Telefunken E88CC in this listing: https://www.ebay.com/itm/266252586987 Professional Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Focal Clear MG Pro open-back headphones Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. Professional testing & sound evaluation Both tubes tested Super Strong NOS (120%+ mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 14,900/14,800 Tube 2: 14,700/15,000 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 stronger. Appearance & Cosmetic condition Beside the world-class sound characteristics, we treasure this pair because of their excellent cosmetic condition. Over 95% of the paint and lettering are still clear on these 60-year old tubes. The 3-line Munich date codes etched on glass are perfectly visible - A0 1# 5D (A0 = E88CC, # = Munich, 5 = 1965, D = April) and A0 1# 5G (A0 = E88CC, # = Munich, 5 = 1965, G = July). Shipping Policy - Ship worldwide! Flat-rate expedited shipping (USPS Priority) within the US. - One business day handling. Orders placed by 2:00PM US Pacific Time on weekdays are posted on the same day, otherwise the next business day. - Combined shipping available - request invoice for total before making payment or receive shipping credit after order ships. - Customers outside the US please pay extra attention: International shipping is through USPS Ground Advantage International 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 us first so we can get you the correct shipping rates before you make payment. Return Policy - Please READ carefully First of all, returns are acceptable as long as you are reasonable. Soundlumia sets extremely high quality standard for the products we deliver. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation before they are approved for listing AND before we ship them to customers. So the defective item case doesnt exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes do not work and we will open a dispute with eBay. Sound experience is a very subjective thing, and lets be real its not that easy to run into compatibility issues between amps and tubes (so that one wont fly, either.) Please contact us to work things out before submitting return requests claiming item is defective or item not as described. We would really appreciate your respect to the professional work we have done (sourcing, testing & matching tubes, evaluating tube sound, sharing our sound experience with you, packing and shipping) to make these wonderful vintage tubes available to you at reasonable prices. Secondly, if you are a tube roller looking to game the return system, Number One STOP. We have seen it all and we know what youre up to. No tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats guaranteed. We have already reported several abusers and eBay has ruled in our favor the dispute cases. We are more determined than ever to continue working with eBay to help rid of these unprofessional, unjustified, unkind, unfair and unacceptable abuses that are detrimental to the eBay marketplace, the vintage tubes market and the audiophile community.

Perfect matched & balanced pair of vintage Siemens CCa Audio Tubes - Munich 1965 - NOS - Extremely Rare Tubes Summary They say only one out of 150 tubes was selected from each batch. They say the design and manufacturing of these was a covert operation only known to the German military. They say the tube specs had not been published until decades later. Be it unverified anecdote, rumor, reverent whisper from audiophiles or innocent misinformation spread by tube enthusiasts totally out of their utmost respect for the sonic wonder of the century, our picky audiophiles ears approve of Siemens CCas superior qualities...on all accounts: matched triode sections, low noise screening, minimum 10,000-hour heater life expectancy, carefully controlled frame grid winding and anti-vibration military build - this is about as good as it can ever get in the entire 6DJ8 tubes family! Sound Qualities As the military version of Siemens E88CC, the CCa tube naturally posses all the greatest traits of the family: the airy and transparent natural tone unrivaled even to this day, the extended yet never tizzy top end, the incisive, neutral and balanced midrange presentation, the clearly defined and deeply controlled bass thats always there with the perfect amount of weight. All these fantastic sound characteristics multiplied by three and thats what you should expect from the Siemens CCa. And the most defining sound characteristic of Siemens tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to reveal the subtle ambient clues that help complete building a truly 3D holographic sound reproduction. The sound stage of Siemens CCa is amazingly wide and feels like the holographic field gets flattened into a panoramic view of your music, still curvy and enveloping, and with added head room - nothing in the sound can escapes your ears (or eyes.) While as quiet and analytical as the Telefunken CCa/E188CC tubes, Siemens CCas also create a warmer, smoother and sweeter German tone (and very German) thats rarely heard elsewhere.

CCa E88CC E188CC 6922 SIEMENS HALSKE MUNICH GERMANY MATCHED QUAD 4 Pcs NOS Code: tubes A6 / 4G and A6 / 3I and A6 /4I and A6 / 4CO-getter,A-frame ,The chrome shieldMany e88cc tubes needed to pair this pair matched to several criteria: date of production - same series and electrical characteristics. such pairing is rareEXTRA MATCHED QUAD !!! EXTRA RARE!!!This version with gold pins is professional and allows work of 10000 hours !!!!It is very difficult to pair 4 tubes and to keep each of them balanced. Before recording the characteristics, all CC tubes are aged for 72 hours in a specially made device and then tested and selected. For these 4 tubes it took over 50 tubes to select a that, you will admit it is very difficult. and theres no need to brag about those tubes - take a look on the net and everything will be clearwhy do I have to age them for 72 hours. Since I give the electrical characteristics of the tubes and for that to be correct, the CC tubes must be forced to work for at least 48 hours in order to equalize the working mode and only then the characteristics are recorded. the current Ia measured on that occasion does not have to be 16 mA and that is 100%, they can be higher and lower, within some limits - there are some on the NET, but it is important that the triodes in the balloon tubes CCa are as uniform as possible . And thats except Ia - mA quality which is primary for me and as a third reference, if I can, give the code .its nice to be harmonized due to the later exploitation of tubes-10000 hours.They are also tested for gas, short and leakageNote: The measurements were carried out with Neuberger RPM370 saw and guarantee for this measurement. The tester has its technical and electrical characteristics that participate in the activities and measuring tubes. Each tube is a special electric circuit that works in conjunction with the saw and this gives measured values. Power saws with classic rectifier and everything else and it has its own impedance, etc ... Digital testers can not give the same measurement results as the classical tester for impedance, reactance, capacitance, conductance, the mode power supply - Switching etc . Tested for NEUBERGER RPM370,Ua=100V,Ug=-1.2V,Ig=16mA=100% two tubes Ia = 15/14 mA and two tubes Ia = 15/15 mA

Perfect matched & balanced pair of vintage Siemens E88CC/6922 Audio Tubes - Munich 1964 - Same date code - Strong NOS Tubes Summary Stronger than time! This is the classic beauty in sound, admired by audiophiles for almost 60 years and will still be our top choice in the next 60 years. Particularly, the early 60s Siemens tone is considered the reference sound for serious classical listeners who need to upgrade the sound quality at phono stage. Sound Characteristics The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens E88CC tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. While as quiet and analytical as the best Telefunken E88CC tubes, Siemens E88CCs produce a warmer, smoother and more musical sound. To see how the two German titans in vintage tube sound compare to each other, please check out our full sound review of 60s Telefunken E88CC here: https://www.ebay.com/itm/266252586987 Professional Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Focal Clear MG Pro open-back headphones Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. Professional Tube Testing Both tubes tested Strong NOS (110%+ mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 14,200/13,900 Tube 2: 14,600/13,900 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. No shorts, gas grid leakages or microphonics. Appearance & Cosmetic condition Despite some loss of paint on one of the tubes, this pair overall is in great cosmetic condition. The identical 3-line Munich date code etched on the glass is perfectly visible on both tubes: A0 1# 4K (A0 = E88CC, # = Munich, 4 = 1964, K = November) Packaging This pair of tubes will be packaged in the new Siemens tube boxes, secured by a hand-made paper ribbon (by courtesy of Soundlumia.) Shipping Policy - Ship worldwide! Flat-rate shipping to all states in the US via USPS Ground Advantage (formerly known as USPS First Class Package.) - Same business day handling. Orders placed by 2:00PM US Pacific Time on weekdays are posted on the same day, otherwise the next business day. - Combined shipping available - request invoice for total before making payment or receive shipping credit after order ships. - Customers outside the US please pay extra attention: International shipping is through USPS Ground Advantage by default. Its the least expensive option and includes insurance up to $100 but it may take longer than other carriers. If you prefer to use a different carrier or if you want to protect your purchase with additional insurance, which we strongly recommend it for orders over $300, please contact us before you buy so we can get you the correct shipping rates before you make payment. Return Policy - Please READ carefully First of all, returns are acceptable as long as you are reasonable. We set extremely high quality standard for the products we deliver. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation before they are approved for listing AND before we ship them to customers. So the defective item case doesnt exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes do not work and we will open a dispute with eBay. Sound experience is a very subjective thing, and lets be real its not that easy to run into compatibility issues between amps and tubes (so that one wont fly, either.) Please contact us to work things out before submitting return requests claiming item is defective or item not as described. We would really appreciate your respect to the professional work we have done (sourcing, testing & matching tubes, evaluating tube sound, sharing our sound experience with you, packing and shipping) to make these wonderful vintage tubes available to you at reasonable prices. Secondly, if you are a tube roller looking to game the return system, Number One STOP. We have seen it all and we know what youre up to. No tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats guaranteed. We have already reported several abusers and eBay has ruled in our favor the dispute cases. We are more determined than ever to continue working with eBay to help rid of these unprofessional, unjustified, unkind, unfair and unacceptable abuses that are detrimental to the eBay marketplace, the vintage tubes market and the audiophile community.
