Perfect balanced Philips SQ E88CC preamp tube - Made in Holland - 1963 - Very Rare
Tube Summary
The beauty, the legend, the classic, the Special Quality(SQ) - this is the super tube from Heerlen's high echelon that doesn't break your bank. Known for their superb musicality and ultra low noise, thanks to Philips' proprietary SQ design, these tubes remain among audiophiles' top choices for critical listening.
Sound Characteristics
Immediately appealing is the super smooth highs offered by these tubes with lots of open air. The overall tonality of SQ is warm, musical and euphonic. The midrange displays some secondary octave nuances, which is very unique and can hardly be found even among the top-end German tubes. Similar to the Telefunken tubes, the SQ's can create infinite levels of harmonic depth and a liquid sonic texture without altering the musicality of the sound. The bass on these is the clear winner of the Heerlen tubes family: articulate, accurate, deep, textured, full-bodied and powerful. The sound stage is wide and structured - it feels the dimensions of the sound shape are clearly defined no matter how it moves.
Vocal representation on the SQ's is close to Mitcham and Blackburn Mullard tubes in terms of warmth, sweetness and texture, making them great alternatives to Mullard's as the best vocals tube. But what truly shines on SQ tubes, especially the ones from the 1960s like this tube, is their magic in portraying piano music: creamy smooth, richly colored, realistic and intimate. For many audiophiles (incl. ourselves), they're the go-to tube for piano sound. Listening to Claudio Arrau's Beethoven Complete Piano Sonatas on these tubes should be on your bucket list if you happen to be into classical piano music, but even if you are not, these tubes' superb "interpretation" of piano music from any genre will amaze you.
The ultra low noise on SQ's also sets them apart from most of the high-end tubes. They don't just compete with Telefunken tubes in low noise; they're known for being a long-term leader in low noise. As a result, you get superb detail and clarity from these tubes as well.
Professional Tube Testing
The tube tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (both in mutual conductance in uMhos and percentage of nominal): 14,500/14,400 (116%/115%)
Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000's 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, it's actually quite straightforward: mutual conductance directly translates to a tube's ability to amplify sound, so the higher the numbers the stronger.
Appearance & cosmetic condition
Besides the world-class sound characteristics, we still treasure this tube for its near pristine cosmetic condition given the tubes' age - over 95% of the paint is still intact, and the date code of the Heerlen factory etched on glass is perfectly visible: delta 3D4 (delta = Heerlen, 3 = 1963, D = April, 4 = Week 4 of the production month)

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."
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 taxes/VAT/GST 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.
