Perfect matched pair of vintage Philips Miniwatt SQ E188CC audio tubes - Made in Holland - 1966 - Very Rare 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 these 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 E188CC tubes, especially the early 60s version like this pair, is their magic in portraying piano music: creamy smooth, richly colored, realistic and intimate. For many audiophiles (incl. myself), 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 are into classical piano music. 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 Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Focal Clear MG Pro open-back headphones Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. Professional Tube Testing Both tubes tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,300/13,800 Tube 2: 13,800/14,000 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 We treasure this pair also because of the great cosmetic condition of both tubes - over 90% of the paint is intact and well preserved. The Heerlen factory date codes etched on glass perfectly visible: delta 6G2 (delta = Heerlen, 6 = 1966, G = July, 2 = 2nd week of the month); delta 6B4 (delta = Heerlen, 6 = 1966, B = Feb, 4 = 4th week of the month) Shipping Policy - Ship worldwide!

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

Perfect matched pair of vintage Philips SQ E88CC audio tubes - Made in Holland - 1962 - Very Rare Note: If you are looking for a single Philips SQ E88CC tube instead of a matched pair, please check out our listing of 1961s Philips SQ E88CC Tube. 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 pair, 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 Sound Evaluation The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring. - Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC - Amplification: Liquid Platinum Tube Amplifier by Alex Cavalli - Output: Focal Clear MG Pro open-back headphones Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above. Professional Tube Testing Both tubes tested NOS (100%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 12,600/12,000 Tube 2: 12,600/12,700 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 pair for its near pristine cosmetic condition given the tubes age - over 90% of the paint is still intact on both tubes, and the date codes of the Heerlen factory etched on glass are perfectly visible: delta 2G4 (delta = Heerlen, 2 = 1962, G = July, 4 = 4th week of the month)delta 2A3 (delta = Heerlen, 2 = 1962, A = January, 3 = 3rd week of the month) Shipping Policy - Ship worldwide!

We are more determined than ever to continue working with eBay to help rid of these unprofessional, unjustified, unkind, unfair and unacceptable abuses that are detrimental to the eBay marketplace, the vintage tubes market and the audiophile community.
