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)
