This auction is for one PAIR of Philips Holland / Pope 6V6GT tubes.
Pope 6V6GT is by far the best example of a 6V6GT ever made. The Pope 6V6GT was made in a Philips Holland factory in Brussels near the border of Belgium and Holland. I have driven by the old factory on my way to the Charleroi airport. This tube was made from 1957 to about 1960. Pope, Adzam, Mullard, and Amperex were names owned by Philips for selling tubes into different areas of the world. Philips really owned the tube industry and were the Microsoft of vacuum tubes.
Upscale Audio has been a player with high-end audiophiles for decades… importing, selecting, and testing New Old Stock tubes and providing only the best for use in the world’s most expensive and exquisite audio components. Not only do we have the largest stock of vintage tubes, we also sell some of the coolest tube gear on the market, including Cary, Quad, Mystere , PrimaLuna , and Peachtree/Decco.
The owner, Kevin Deal, has been a veteran of the industry since 1978. Kevin’s tube hunting trips to Europe in search of lost inventories are legendary. Is a world-renowned authority on vacuum tubes, particularly their relationship to audio components and has been interviewed by the likes of The New York Times, The Absolute Sound, Soundstage! and Lightning Magazine in Japan.
First, all our tubes are burned in to ensure stability and to weed out potential problems. Power tubes are aged for 72 hours on our custom-built TubeZilla and Son of TubeZilla; fully regulated test and burn-in racks. After completing the burn-in, our technician measures the bias requirements of each tube on our exclusive TM-101 tube matcher, where they are screened for excessive screen current draw. Finally, using the measurements realized by our TM-101 as a guide, our tech groups power tubes into matched quads (sets of four), where each tube is closely matched to the other to ensure the best sound and tubes that age gracefully together. Of course, matching in any quantity necessary (pairs, quads, sextets, octets) is also available and included free of charge.
Preamp tubes undergo a slightly different test before they can make the Upscale Audio grade. After burn-in, each tube is measured for transconductance. Next, our tech places them into a simulated phono stage where he examines each tube carefully and grades them for noise and microphony.
Warranty: Upscale Audio extends a 90 day warranty from day of purchase on these vacuum tubes. Tubes are warranted against defects, except in cases of abuse, and replaced with like-item only. Tubes are electronic parts and therefore are not refundable. Upscale Audio is not liable for any damage or injury caused by the improper use of its tubes or the use of an incorrect/incompatible tube type. If you are unsure of what tube or tubes your equipment uses, consult the manufacturer before making a purchase. Using an incompatible tube type may cause severe damage to your equipment and will void your tube's warranty.
