Perfect balanced Philips SQ E88CC preamp tube - Made in Holland - 1961 - Very Rare Note: If you need a pair of early 1960s Philips SQ E88CC tubes instead of a single tube, please see our listing of 1962 Philips SQ E88CC Tubes Matched Pair. Tube Summary The beauty, the legend, the classic, the Special Quality(SQ) - this is the super tube from Heerlens high echelon that doesnt 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 serious 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 SQs 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 SQs is close to Mitcham and Blackburn Mullard tubes in terms of warmth, sweetness and texture, making them great alternatives to Mullards 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), theyre the go-to tube for piano sound. Listening to Claudio Arraus 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 SQs also sets them apart from most of the high-end tubes. They dont just compete with Telefunken tubes in low noise; theyre 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 OS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): 14,700/14,900 Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s 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, its actually quite straightforward: mutual conductance directly translates to a tubes 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 1G5 (delta = Heerlen, 1 = 1961, G = July, 5 = 5th week of the month) Shipping Policy - Ship worldwide! Flat-rate shipping (USPS First-Class) within the US. - Same business day handling.

Return Policy - Please READ carefully First of all, returns are acceptable as long as you are reasonable. Soundlumia sets extremely high quality standard for the products we deliver. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation before they are approved for listing AND before we ship them to customers. So the defective item case doesnt exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes do not work and we will open a dispute with eBay. Sound experience is a very subjective thing, and lets be real its not that easy to run into compatibility issues between amps and tubes (so that one wont fly, either.) Please contact us to work things out before submitting return requests claiming item is defective or item not as described. We would really appreciate your respect to the professional work we have done (sourcing, testing & matching tubes, evaluating tube sound, sharing our sound experience with you, packing and shipping) to make these wonderful vintage tubes available to you at reasonable prices. Secondly, if you are a tube roller looking to game the return system, Number One STOP. Soundlumias founder is a seasoned sound professional who has advised orchestras and music studios in sound production in USA for over two decades, so knowing sound is the minimum skill requirement of our team. We are experts in sound and equipment - tubes, headphones, speakers, DACs, amps, turntables, CD Players - you name it. So no tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats also guaranteed. We have already reported several abusers to eBay and we are determined to continue working with eBay to help rid of these unprofessional, unjustified, unkind, unfair and unacceptable behaviors that are detrimental to eBay, the vintage tubes market and the audiophile community.

E188CC E88CC 6DJ8 ECC88 6922 PHILIPS MATCHED PAIR NOS 2pcsGold pins,10000 h,grey anode plates,o geter,tested,with boxThe Philips Holland SQ E188CC / 7308 Gold Pin is the holy grail of lush 6922 tone. These are right up there with Telefunken CCa and Siemens 7308 when it comes to rarity. To our ears these sound more musical than the Siemens or Telefunken. These have a large round getter and beautiful construction.EXTRA TUBES GREAT SOUND!!!!!!EXTRA MATCHED!!!EXTRA BALANCED!!!All the tubes that were sold worked for 72 hours on the aging device to stabilize and in order to capture the characteristics. otherwise, in practice, some tubes quickly change the characteristics that deviate from the given values of the anode current Ia. there can be a misunderstanding. so the pipes are allowed to work 72 hours in order to get as much to their proper characteristic.They are also tested for gas, short and leakageNote: The measurements were carried out with Neuberger RPM370 saw and guarantee for this measurement. The tester has its technical and electrical characteristics that participate in the activities and measuring tubes. Each tube is a special electric circuit that works in conjunction with the saw and this gives measured values. Power saws with classic rectifier and everything else and it has its own impedance, etc ... Digital testers can not give the same measurement results as the classical tester for impedance, reactance, capacitance, conductance, the mode power supply - Switching etc .Date code VR7??? / delta8K? and VR7???/delta8I4Tested for NEUBERGER RPM370,Ua=100V,Ug=-1.2V,Ig=16mA=100% Ia = 16/16mA and Ia = 16/6mA

Probably no one in this world has a pair of CCs like this because there are NO more of them !!This version with gold pins is professional and allows work of 10000 hours !!!!It is very difficult to pair 4 tubes and to keep each of them balanced. Before recording the characteristics, all CC tubes are aged for 72 hours in a specially made device and then tested and selected. For these 2 tubes it took over 50 tubes to select a that, you will admit it is very difficult. and theres no need to brag about those tubes - take a look on the net and everything will be clearwhy do I have to age them for 72 hours. Since I give the electrical characteristics of the tubes and for that to be correct, the CC tubes must be forced to work for at least 48 hours in order to equalize the working mode and only then the characteristics are recorded. the current Ia measured on that occasion does not have to be 16 mA and that is 100%, they can be higher and lower, within some limits - there are some on the NET, but it is important that the triodes in the balloon tubes CCa are as uniform as possible . And thats except Ia - mA quality which is primary for me and as a third reference, if I can, give the code .its nice to be harmonized due to the later exploitation of tubes-10000 hours.They are also tested for gas, short and leakageNote: The measurements were carried out with Neuberger RPM370 saw and guarantee for this measurement.
