Perfectly balanced vintage Amperex 7308 PQ audio tube w/ D-getter - Made in USA - 1960 - Strong NOS - Early VR0 type - 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 100% balanced Amperex 7308 PQ D-getter with the VR0 control code for early type from 1960, one of the greatest years for Amperex USA and one of the very few years in which these d-getter tubes were ever manufactured. And the sound from this gem is as good as it USA White Label tubes can ever get. We have recommended PQs to a great number of wonderful patrons of Soundlumia, 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 ones made in Hicksville, New York are 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. The sound 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 the PQs to so many satisfied customers who used them in phono preamp 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 as a sound purifier 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. Lastly, the cherry on top: the super rare D-getter (only manufactured in the late 1950s and 1960) on these tubes further refines your sound: cleaner instrument separation, smoother top end, taller imaging and MUCH more details! Appearance & cosmetic condition Beside the world-class sound characteristics, we treasure this tube for its pristine condition - nearly 90% of the paint is intact, and the date code etched on glass is perfectly visible: VR0 *0L (VR0 = change code, * = Amperex New York factory, 0 = 1960, I = September) Professional Tube The tube tested Strong NOS (110%+ mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance both in uMhos and in percentage of nominal): 14,000/14,000 (112%/112%) 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. Shipping Policy - Ship worldwide! Flat-rate expedited shipping (USPS Priority) 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. Please 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 First Class Mail International by default. Its the least expensive option (even cheaper than eBay International Shipping) but 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 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.

Fine pair of Amperex JAN 7308 gold pin tubes. Closely matched to about 4% difference between sections and tubes. From a large lot of identical tubes (as shown in the last picture), all with 1967 date codes. The codes on these two tubes have been worn off, but others from this lot are VR5 *7I or VR5*7J. Please note that youre buying only the PAIR shown here, not the entire lot. If you need more than one pair, I can list others for you. I ship worldwide directly via USPS and UPS. Buyers from mainland China and Italy: please contact me for shipping cost.

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. Tubes are not tested for noise or microphonics. 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 total $400 or less are generally shipped via the USPS Ground Advantage service, while orders exceeding that value 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 ship to China and Italy only via UPS Worldwide Expedited, regardless of value. No exceptions. I dont use eBays in-house International Shipping program, as the cost tends to be much higher than shipping directly with a carrier.USPS requires 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. R31

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.
