Philips E188CC = 7308 Matched Pair - Lorenz/Dario Labels

Description: Tube Summary The "textbook Heerlen sound" has been referenced in several Soundlumia listings of Amperex Holland/Philips E88CC/6922 tubes, and many tube enthusiasts asked what that all means. So this is the answer: the late 1950s and very early 1960s tone, the beginning of over a decade's excellence in sound, the classic tonal template for all the great (and greater) Amperex/Philips/Valvo/Miniwatt tubes to be made in the years to come, the timeless Philips radio tone that many of us grew up listening to. And this super rare E188CC pair is the "further amplification" of all that. Sound Characteristics Be assured - you will not miss one single bit of the legendary Heerlen sound just because the tubes are not labeled Philips. 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 the top choice if you look for the finest sound details and ultra clarity.

Professional Tube Testing This set was tested and certified by RoeTest V11 tester with the following result: Tube 1: Measured transconductance (GM): 12.01/12.58 mA/V - 96%/101% (100% = 12.50 mA/V)Measured plate current (IA): 14.729/17.174 mA - 87%/101% (100% = 17 mA) Tube 2: Measured transconductance (GM): 12.89/13.29 mA/V - 103%/106% (100% = 12.50 mA/V)Measured plate current (IA): 16.394/17.436 mA - 96%/103% (100% = 17 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 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: ⊿2K (⊿ = Heerlen, Holland, 2 = 1962, K = November) Packaging NEW reproduction Philips tube boxes.

Return Policy - Please READ carefullyReturns 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.
