Amperex 7025 12AX7 Matched Pair - Holland 1967 - Orange Globe - Same code

Description: Perfectly matched & balanced pair of vintage Amperex 7025 Orange Globe audio tubes - Holland 1967 - Extremely strong NOS - Identical date code Product Summary And the award of "the quietest tube on the planet" goes to...Amperex Holland 7025! Virtually identical to ECC83/12AX7 but with nearly non-existent hum and noise thanks to the unique spiral wound filament design that effectively packs two tubes in one glass envelop, the Holland made 7025 tubes preferred by audio professionals and hardcore enthusiasts. Sound Qualities We have evaluated at least 10 different versions of Orange Globe tubes and the mid-1960s' Holland sound is clearly among the best. You get the "textbook" Amperex Holland midrange presentation that is transparent, natural and expansive, with a slight touch of warmth that illuminates your musical world. The top end is super airy, smooth and nicely extended like one would expect from the best Siemens tubes. Vocals are intimate, sweet and forward (but not right in your face) and that always reminds me how the vocals sound on the best Mullard tubes. Bass is deep and well controlled and the accuracy feels very similar to the high end German ECC83's (Siemens, Telefunken.) To see how these sound differently from their German counterparts, please feel free to take at a look a wonderful pair of Telefunken ECC83 tubes in NOS condition from 1967 we have in stock here: https://www.ebay.com/itm/266468275446 Professional Tube Testing Both tubes tested Super Strong NOS (120%+ nominal mutual conductance) on a reliable and recently calibrated Mercury 2000 tube tester with the following results for mutual conductance both in uhMos and percentage of nominal: Tube 1: 1,430/1,400 (143%/140%)Tube 2: 1,390/1,400 (139%/140%) Good tubes start at 700 and new tubes (incl. NOS/NIB) 1,000, and the Mercury 2000 tester's rated mutual conductance (nominal) for new tubes is 1,000. Test results can be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to a tube's ability to amplify sound, so the higher these numbers the stronger. No short, leakage or gas. Appearance & cosmetic condition we treasure this pair because the pristine cosmetic condition the two tubes are in - over 90% of the paint is intact. The identical Heerlen date codes etched on glass are perfectly visible on both tubes. What a rare find! delta 7H1 (delta = Heerlen, Holland, 7 = 1967, H = August, 1 = 1st week of the month) Packaging This pair of tubes will be packaged in the original Amperex 7025 tube boxes secured by a hand-made paper ribbon (courtesy of Soundlumia.)

Return Policy - Please READ carefully Returns are acceptable in the case that we made a mistake by delivering you wrong or defective products. All of our tubes are guaranteed to arrive in the exact condition as described in our listings. We run professional tube tests + sound evaluation TWICE: before they are approved for listing AND before we ship them to customers. That means there's no possibility of you receiving a "defective item", therefore there is no plausible way for a customer to try returning a tube by reporting it as "defective". This type of return will NOT be accepted without proof that the product is faulty. A dispute will be opened with eBay in this scenario. We do NOT accept returns for buyer's remorse which includes customers who decide they don't like the subjective tonal signature of a tube. Please contact us to work things out before submitting return requests claiming "item is defective" or "item not as described." 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. 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.
