Tubes Summary
Our best seller is back in stock - the Amperex USA PQ White Label! This listing is for a 100% balanced Amperex 6922 PQ D-getter 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 PQ's 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 PQ's 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 PQ's (Made in Gt. Britain w/ Heerlen date codes) and USA PQ's 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:
7L4 *0A = (7L4 = E88CC, * = Amperex New York, 0 = 1960, A = January)

Return Policy - Please READ carefully
Returns are acceptable if we made a mistake by delivering you wrong or defective products. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation TWICE: before they are approved for listing AND before we ship them to customers. So the "defective item" case doesn't exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes are faulty and we will open disputes with eBay. Sound experience is very subjective and we do NOT accept returns because you do not like the tube's sound signature or because you changed your mind about your purchase. Please contact us to work things out before submitting return requests claiming "item is defective" or "item not as described" or "just didn't like it" or "changed my mind."
Tube rollers abusing the return system will be reported to eBay immediately and negative feedback will be left to your account - that's guaranteed. We have already opened several dispute cases to report abusive buyers and eBay has always ruled in our favor. International buyers who request return or refund claiming your country's import duties or sales tax/GST/VAT are too high will be reported to eBay immediately for dishonesty and will be permanently blacklisted from purchasing from Soundlumia. We are committed to working closely with eBay to help rid the marketplace of dishonest, unjust, unreasonable, abusive buyers that are detrimental to the vintage tubes market and the audiophile community.
