Perfect matched pair of vintage Mullard E188CC audio tubes - Made in Holland - 1964 - Identical Date Code - Very Rare Tube Summary This is not a listing about audio tubes but an invitation to hear the the sweetest voice on Earth. Yes no other tubes can deliver vocals like the Mullards, whether theyre from Blackburn, Mitcham, or Heerlen, and thats a fact. The Mullard labeled and Holland made E188CC tubes are extremely hard to find today and are being hunted to extinction by audiophiles and sound professionals. Sound Characteristics Be assured - you will not miss one single bit of the legendary Heerlen sound just because the tubes are labeled Mullard. The proud delta symbol in the date code tells you this is 100% textbook natural sound from Heerlen: warm and lively tone with infinitely expansive midrange and nice extension on both top and low ends. The technical advantages of the E188CC/7308 design on these tubes have taken sound to the next level: you get more forward vocals and a wonderful airy top end, super large imaging and incredibly spacious sound stage. Like any other E188CC/7308 tubes, they have low noise to the vanishing point, and that makes these tubes also one of the go-to tubes for details & clarity. 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 (100% - 110%+ mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 13,000/12,600 Tube 2: 12,800/12,600 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 better. Appearance & cosmetic condition We treasure this pair also because of the pristine condition of both tubes (clear inscription and clear date codes), which is amazing given the tubes age. What makes this pair even more rare is the identical date code on both tubes: delta 4C1 (delta = Heerlen, 4 = 1964, C = March, 1 = 1st week of the month) Shipping Policy - Ship worldwide! Flat-rate shipping within the US. - Same business day handling. Orders placed by 2:00PM US Pacific Time on weekdays are posted on the same day, otherwise the next business day. - Combined shipping available - request invoice for total before making payment or receive shipping credit after order ships. - Customers outside the US please pay extra attention: International shipping is through USPS First Class Mail International by default. Its the least expensive option (even cheaper than eBay International Shipping) but may take longer than other carriers. If you prefer to use a different carrier please contact us before you buy so we can get you the correct shipping rates. 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, and knowing sound is the minimum skill requirement of our team. 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.
