Mullard E88CC/01 = CV2493 (Mil. Spec E88CC) Matched Pair – Mitcham '71/'73 7L1

Soundlumia’s Opinion The “Super Mullard” is here! E88CC/01 (a.k.a CV2493) – fully equivalent to E88CC/6922 but a HUGE step-up in both sound quality and build. Most of these tubes were factory screened for tight internal matching and low noise, and Mullard’s E88CC/01 type has even more factory testing. Manufactured in very limited quantity (simply because the selection standard was too high for mass produced tubes to meet) and today they are being hunted to near extinction by audiophiles, tube enthusiasts and sound professionals. “Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions.” This is how experts on audiotubes.com describe the sound signature of British-made Mullard tubes. The top end is silky and pleasant and doesn’t get rolled off. They retain a fine sense of “air” at the top, and the upper midrange is smooth and liquid. These tubes reproduce human voice, especially female voices, with haunting realism. Listening to Maria Callas and Frank Sinatra on British-made Mullard tubes should be one of those musical experiences that one just has to go through at least once in his lifetime. These tubes are also known to have an attractive sparkle at the top with rich bass…now we know where that “warm British jacket” comes from! Now all those great traits of Mullard tubes you have heard about or have experienced already multiplied by three and that is what you should expect to hear from this pair of E88CC/01’s. 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 This set was tested and certified by RoeTest V11 Professional Tube Testing System with the following result: Tube 1: Measured transconductance(GM): 10.11/8.23 mA/V – 81%/66% (100% = 12.50 mA/V) Measured plate current(IA): 11.692/6.99 mA – 78%/47% (100% = 15 mA) Tube 2: Measured transconductance(GM): 10.7/10.8 mA/V – 86%/86% (100% = 12.50 mA/V) Measured plate current(IA): 9.855/9.577 mA – 66%/64% (100% = 15 mA) NO shorts, leakage or gas. NO noise or microphonics. Curve trace is also included in the original RoeTest report. Appearance & cosmetic condition We treasure this pair also because of the great cosmetic condition of both tubes (clear inscription and clear date codes), which is amazing given the tubes’ age. The identical Blackburn date code etched on glass is perfectly visible on both tubes: 7L1 R3K1 ( R = Mitcham, GB, 3 = 1963 , K = November, 1 = Week #1 of the production month) 7L1 R1J1 ( R = Mitcham, GB, 1 = 1961 , J = October, 1 = Week #1 of the production month) Shipping Policy – US Shipping: Flat-rate USPS Ground Advantage (upgradable to flat-rate USPS Priority or FedEx 2nd Day for expedited delivery.) – International Shipping: Flat-rate USPS First Class International (upgradeable to flat-rate UPS Worldwide Expedited or DHL Express for expedited delivery.)

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” or “changed my mind.” 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 tax/GST/VAT 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.
