TESTING ACCORDING TO DATA SHEETS FOR 8416’S ARE AS FOLLOWS: 90 PLATE VOLTS, MARGINAL  THIS PAIR MEASURES: 35, 34ma.  THIS IS A REAL WORLD TEST OF THE TUBE. We tested it with the same voltages it will see in a real application circuit. Most testers cannot put the proper plate voltages on a tube and cycle through stepped grid voltages like we do with 576 CURVE TRACER. OK, here they are......these are the tubes you have been looking for! These are PQ AMPEREX 8416s. For audiophiles these tubes are the sweetest sounding tubes made.  Once they are gone I have NO MORE. These tubes are perfect for use in the  Lampucera1.0 + Lampizator CS8416 + CS4397. This guy does some fantastic work in taking the signal straight out of a DAC and before it get mucked up by the OPAMP he steals the pure analog signal and routes it to the 8416 which is just a 12 volt 6922.  The signal can then be fed into you headphone am for pure sound. AWESOME!!! Some folks say these 12 volt versions of the vaunted Amperex 6922s sound better than the 6 volt versions. I dont know if that is true, but they are every bit as good. On my tester a B&K 747 tester:    Below 55 = BAD      55-65 = ?     65 -100 = Good     100-120+ = NOS     I want to see you happy with your purchase. I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !! 1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer. If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button. Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping. 2.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! 4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days. 4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.   Listing and template services provided by inkFrog

Perfect matched & balanced pair of vintage Amperex 6922 PQ audio tubes w/ D-getter and gold pins - Made in USA 1959 - NOS - Ultra Rare Soundlumia officially recommends Amperex PQ 6922 & 7308 USA White Print tubes to be used in phono preamps based on extremely positive feedback from our past and repeat customers around the world. Tubes Summary Our best seller is back in stock - the Amperex USA PQ White Label! This listing is for a tightly matched pair of d-getter tubes with identical date code from 1959, one of the best years of Amperex USA and and very rare to find today. We have recommended PQs to more than 15 wonderful patrons of the Soundlumia eBay store, who are enjoying these tubes in their class leading amplifiers from Audio Research, Ear, Schiit Audio and Cavalli etc. and raving about their unquestionable superiority in sound. Sound Qualities Among all the PQ tubes, the USA white print version (made in Hicksville, New York) is the most sought after by serious audiophiles and tube enthusiasts. They are as sweet and smooth as the Amperex Holland PQ tubes, with even better detail and very spacious sound stage, which offers an amazing birds eye view of the shape of your sound, so you know exactly how tall and wide the sound stage is. The tone is warm yet lively, mids are forward but also expansive like what you hear on their cousins from the Holland factory, bass is punchy but not heavy. We have recommended them to so many satisfied customers that we have given them a nick name sound purifier - the sound that comes from these tubes has absolutely no edginess, glassiness or harshness, and you hear nothing but the soul of your music and all of it. They are the best tubes to to put in the phono stage to purify your sound in my opinion. As to vocals, I have no further comment than that the best Mullards were actually sourced from Holland PQs (Made in Gt. Britain w/ Heerlen date codes) and USA PQs beat the Holland ones in vocals period. Listening to Righteous Brothers Unchained Melody through these PQ tubes should be on your bucket list, no matter what type of music you enjoy. At this level of the game, the USA PQs compete with the premium German E88CCs made by Siemens and Telefunken (other brands dont even come close), and always come ahead in midrange presentation and overall musicality, and they have the best value at this price. For comparison of sound characteristics, please feel free to check our listing of a pristine matched pair of 1962 Telefunken E88CCs here: https://www.ebay.com/itm/266264647552 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 NOS (100%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,000/13,500 Tube 2: 13,000/13,000 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. No shorts, gas grid leakages or microphonics. Appearance & cosmetic condition This pair of PQs are so rare because nearly 100% of the inscription (Amperex brand, Made in USA print and PQ logo) is intact. The identical Amperex New York factory date code etched on glass is perfectly visible on both tubes: *9K (* = Amperex New York, 9 = 1959, K = November.) Shipping Policy - Ship worldwide! Flat-rate shipping (USPS First-Class) within the US. - 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.

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. Soundlumias founder is a seasoned sound professional who has advised orchestras and music studios in sound production in USA for over two decades, and knowing sound is the minimum skill requirement of our team. 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.

These deliver absolute heavenly bliss!!! So..... here they are......these are the tubes you have been looking for! These are  AMPEREX PREMIUM QUALITY PQ 6922s. A near perfect pair with no wear or blemishes and they sound perfect (tested by me). For audiophiles these tubes are the sweetest sounding tubes made.  Once they are gone I have NO MORE. You may never see tubes like this again. I have only ever seen a few in all my years. Heres what tube guru Brent Jesse says concerning these tubes: This is probably the ultra 6DJ8 type tube commonly available. It has all of the features of the 6DJ8, but the triode sections are also matched to each other, and the tubes all fit within very tight specifications. Therefore, any 6922 should match any other 6922 within the same brand. The Amperex versions were again made in New York, complete with gold pins, and often have a number etched into the side of the glass. Amperex made these for industry as well as the military. The Amperex versions have the PQ label, the military type usually is labeled USN_CEP, but I have seen versions made for Stromberg-Carlson and Hewlett-Packard, with white ink labels. These all had the numbers etched into the glass, and all are the same tube. The USA made military white label types have been rated Best of All, over other 7308, 6922 and even Cca tubes, in several well-documented 6922/7308/Cca listening tests. Therefore this particular type is becoming scarce and prices are rising. There were a few of these made in Holland, but most were made in the USA, therefore the Holland tubes are RARE and usually command a higher price. The Holland PQ versions have the PQ with stars on either side of the letters, and the words Premium Quality, where the USA types have the PQ inside of a shield logo.  Rated Best of All in 7308/6922 and Cca listening tests!

I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !! 1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer. If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button. Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping. 2.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! 4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days. 4.

Beautiful pair of Amperex PQ 6922 E88CC gold pin tubes, with original boxes. White print on the glass, large O getters. Identical 1962 USA date codes. Buyers from mainland China (not including Hong Kong): due to excessive losses and delays within your postal system, I will ship to you only via UPS. You must select UPS (not USPS) from the shipping options when you purchase.

I have over 30 years of experience as an electronics engineer, certified electronics technician, and hobbyist, and have been collecting, buying, and selling tubes since the 1980s. Ive been an eBay seller since February of 2000. This is the only seller account I have on eBay and the pictures you see are of the actual tube(s) you’ll receive. Tubes are described, tested, and presented to the best of my ability, subject to the limitations of the equipment that I have available (Hickok 539C and 6000A). Test results are likely to differ between your equipment and mine due to many factors, and tubes are not tested for noise or microphonics. Discrepancies between your test results and mine, or the presence of noise or microphonics, do not qualify tubes as “defective” or “not as described,” as such variations are common and to be expected. Do you have tubes to sell? Contact me with your inventory!Return Policy Unless otherwise stated in this listing, tubes may be returned within 30 days for a refund. Please keep in mind that while I do allow returns, my purpose here is to sell tubes, not to loan tubes for rolling. Any tube to be returned must: a) still bear my identification stamp. b) be in EXACTLY the same condition in which it arrived to you. Things which may invalidate a return: defaced or smudged print on the glass, bases scratched from retainer springs, cracked or damaged glass, damaged or missing boxes (where original boxes were sent with the tubes), and electrical or physical degradation from improper operation or handling. Returns which do not meet the above criteria may be refused or may be subject to partial refund. Ebays return guidelines prohibit “using or damaging an item and then returning it.” I pay for return shipping on all returns within the USA, regardless of reason. You pay for return shipping if you are located outside of the USA. If the tube arrives to you DOA or significantly not as described (SNAD) I pay for return shipping. I do not pay for return shipping for any other reason. If a tube is returned as DOA or SNAD, but does not test as such upon return, I reserve the right to be reimbursed for any return shipping cost that I paid. International buyers, please note: Import fees and taxes which you pay to your border and/or customs agency are not refundable by me under ANY conditions or for ANY reason, regardless of the reason for your return. Shipping Your tubes will be professionally prepared for shipping using all-new packing materials and will arrive to you in perfect condition. Ive been shipping tubes for many years and know how to get them to you quickly and securely. International orders ship with proper customs documentation and tariff codes to ensure that theyre processed with minimal delay upon arrival in the destination country. DOMESTIC: Unless otherwise noted, free shipping is offered on all tubes purchased with Buy-It-Now. Orders that weigh 16 oz. or less and which total $400 or less are generally shipped via the USPS First Class Package service, while orders exceeding either of those values are shipped via USPS Priority Mail. Other services are available at additional cost. If you prefer a shipping method that is not listed, please contact me prior to purchasing. I can usually ship via any USPS, FedEx, or UPS method that is applicable to your ZIP code. If you need expedited shipping (Express, Next Day, etc.) please contact me first to confirm earliest available date of shipment, as cutoff times are generally early in the afternoon. INTERNATIONAL: USPS First Class Mail: This is the least expensive option but the availability of tracking is limited in many cases. Its available worldwide for packages with a value of USD$400 or less. Be aware that First Class Mail has been known to take up to three months to reach some destinations. Customs delays are also more common with First Class. If you select the First Class option I expect that you will be patient and wait three months before requesting a refund for “item not received.” If you require faster delivery please select an option below. USPS Priority Mail: This option is available for shipments with a value less than USD$1000. It typically takes a couple of weeks to reach most destinations. UPS Worldwide Expedited: This option is available worldwide for all shipments, and is required for shipments valued at USD$1000 or more. It is fast and reliable, with end-to-end tracking. I can also usually arrange shipping with other carriers at additional cost. Please inquire before purchasing if you have specific requests. I no longer ship to Italy. I ship to China only via UPS Worldwide Expedited, regardless of value. No exceptions. Orders valued in excess of USD$2000 may be shipped in multiple packages. Dont put too much faith in eBay delivery estimates for international shipments. They are often wrong by a considerable amount. I dont use eBays Global Shipping Program (GSP) because they treat tubes as hazardous material and will confiscate them.USPS is now requiring that all addresses be in “Latin” (abcdefg) characters (this means, for example, no Cyrillic (???????) or Chinese (???), etc.). USPS will return to the me any packages which violate this guideline, and the buyer will then be required to correct the address and pay postage again. Ebay places the burden of safe delivery on sellers, so I fully insure all shipments sent outside of the USA, regardless of value. Because I can insure only up to the declared value, ALL SHIPMENTS ARE DECLARED AT ACTUAL VALUE. You might owe significant import fees on higher value shipments once they cross your countrys border – check with your border or customs agency for details. I can ship to a domestic freight forwarder or other third party within the USA, provided their address is on the order at the time you place it. GENERAL: SIGNATURE REQUIREMENT: All orders valued at USD$750 or greater, and ANY order shipped via UPS or FedEx, automatically require a signature release upon delivery. Someone at your delivery address will need to be available at the time of delivery to sign for the package. COMBINED SHIPPING: Im happy to combine shipping on multiple purchases. Those shipping within the US will combine automatically. International orders must be manually combined after the purchase, and any excess shipping will be refunded to your payment source (due to the way eBay buy-it-now items are set up, this is the only way I can combine shipping on more than one item). HANDLING TIME: My handling time is one business day and eBay requires me to ship within that timeframe. I cannot withhold shipment for a later date. If you require shipment on a specific date I can often set up a special listing just for you on that date; please inquire. I usually ship every day of the week, except for Sunday and USPS-observed holidays, and orders often ship same day. Orders placed later in the day usually ship next business day. Orders placed on Friday or Saturday will sometimes not ship until Monday. All orders placed on Sunday or USPS-observed holidays ship the next business day. Expedited and express shipments (FedEx and UPS 2-day & Next Day, etc) must be placed by 12PM Pacific Time in order to ship same day. If you have an urgent delivery need its a good idea to contact me first so I can confirm exact day of shipment. SHIP-TO ADDRESS: Ebay requires that I ship to the address on the order. This protects both you and me. I cannot ship to a different address. If you require shipment to a different address please update your shipping information before making a purchase. R27

2 Amperex PQ E88CC/6922 O-Getter Gold Pin tubes. Nice set for your audiophile needs. From private collector and been treated well.

Perfect matched & balanced pair of vintage Amperex 6DJ8 (ECC88) PQ audio tubes - Made in Holland 1962 - Dimple Disc Getter - Strong NOS - Very Rare Tube Summary Enjoy the most musical 6DJ8/ECC88 tube on Earth - Amperex 6DJ8 PQ (Premium Quality) made in Holland from the early 1960s! PQ tubes are among the greatest Amperex tubes ever made and are highly sought after by serious audiophiles. These prestige tubes were made with special filament technique to produce special quietness in sound - something one can only find on Philips SQ (Special Quality) or high-end German E88CC tubes. Sound Characteristics As a major step-up of the famed early production of Amperex Holland tubes with steel pins (Bungle Boys, Orange Globe etc.), these tubes combine the best of both worlds: the large sound stage, transparent midrange and liquid & harmonic sound from the Bugle Boy & Orange Globe, and the laser precision imaging and superb smoothness in the top end from the PQ series. We have recommended PQ tubes to so many satisfied customers who use them in their phono setup that we have given them a nick name sound purifier - the sound that comes from these tubes has absolutely no edginess, glassiness or harshness, and you hear nothing but the soul of your music and all of it. These are the best tubes to to put in the phono stage to purify your sound. Appearance & Cosmetic condition This pair is so rare because nearly 100% of the paint is intact on both tubes, and Heerlen date codes etched on glass are perfectly visible: delta 2F1 (delta = Heerlen, Holland, 2 = 1962, F = June, 1 = 1st week of the month) delta 2J2 (delta = Heerlen, Holland, 2 = 1962, J = October, 2 = 2nd week of the month) 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: Clear Focal 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%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,800/13,800 Tube 2: 13,200/13,900 Good tubes start around 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and 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 would 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. Shipping - 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. - Ship worldwide! Flat-rate shipping within the US. 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: Delivery will be through eBay International Shipping 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 before you buy so we can get you the correct shipping rates. Return & Exchange First of all, returns/exchanges are acceptable as long as you are reasonable. Soundlumia sets extremely high standard on the quality of products we deliver. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation before they are even approved for listing. However, sound experience is a very subjective thing and its not uncommon to run into combability issues due to different amp designs, please contact us to work things out before submitting returns or opening a defective or item not working case on eBay. We would really appreciate your respect to the professional work we have done (sourcing, testing & matching tubes, evaluating tube sound and sharing tube sound review with the world through this listing) 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. Soundlumias founder is a sound professional who has advised orchestras and music studios in sound production in the USA for over two decades, so knowing sound is the minimum skill requirement of our team. We are experts in sound and equipment - tubes, headphones, speakers, DACs, amps, turntables, CD Players - 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.
