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!

No tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats guaranteed. We have already reported several abusers and eBay has ruled in our favor the dispute cases. 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.

I have for sale a E188CC 7308 Vintage Miniwatt Holland tube. Etch code R7 812 with preceeding delta mark On AVO MKIV new tubes test 12 ma this tests 10ma on both sections - strong desired tube Tube Testing: Unless stated new old stock all tubes are used. I test all tubes for shorts, filament and emission. All my testers including AVO MK IV , Lafayette etc are vintage, and I have not had them calibrated in decades. For this reason I no longer list the emission readings of tubes as they would not be precise. The AVO MK IV still to this day is regarded as one of the best tube testers ever made. I personally think the AVO MKIV is the best for testing most tubes with the exceptions of 12ax7 and ECC88 etc which I feel the results are accurate but not precise. I only list good testing tubes and have been around tubes for many years and as always stand by every tube I sell and have excellent feedback I PACK ALL TUBES VERY WELL FOR SAFE TRAVEL AS REFLECTED IN FEEDBACK.No longer post to China as I will not declare lower value for customs as it is illegal to do soUnless stated New Old Stock all tubes are used I NO LONGER POST ITEMS TO ITALY, GREECE, RUSSIA , MEXICO ETC DUE TO POSTAGE DELAYS For buyers in Europe and parts of Asia that have high import duties, please remember I do not falsify customs forms so please be aware of your own regulations.
