Reflektor 6N23P = E88CC Silver Shields SWGP Matched Pair - USSR '74

Description: Soundlumia's Opinion 6N23P (Russian name: 6H23) tube is equivalent to European E88CC/6922 tubes. Designed to work in amplifiers and pulse generators, they are guaranteed to deliver high durability (at least 5,000 hours life), reliability and mechanical strength. This pair come with the special OTK purple stamp, a proud statement of the highest standard in testing and the privilege of being selected by the Soviet's State Control Bureau (OTK) for export and government use. These two tubes in particular also have colored tips (red and green), which are a symbol of select tubes for military or medical use. With premium quality in both build and sound, the Reflektor 6N23P's are the top choice among Soviet-made vintage tubes and also a great alternative to the expensive European E88CC's. Like most of the Reflektor tubes (from both the 1960s and the 1970s), the 1974's have beautiful airy highs and sound very natural. They excel in sound detail and clarity, and overall tonality is warm, rich and relaxed. The sound stage produced by these tubes is spacious and holographic, very similar to the German E88CC's. They are very fast tubes, as in solid state fast and precise, but with tube liquidity and warmth. There is an immediacy to the sound, crisp and tonally dense, never etched or brittle. These are among my go-to tubes for late night movies when I switch my entire sound world to the headphone stack because you can listen to the movie sound on them for hours nonstop and don't feel fatigue at all. 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 TestingThis set was tested and certified by RoeTest V11 Professional Tube Testing System with the following result: Tube 1: Measured transconductance(GM): 10.98/9.58 mA/V - 88%/77% (100% = 12.5 mA/V)Measured plate current(IA): 9.367/9.825 mA - 62%/66% (100% = 15 mA) Tube 2: Measured transconductance(GM): 9.9/10.25 mA/V - 79%/82% (100% = 12.5 mA/V)Measured plate current(IA): 10.657/11.152 mA - 71%/74% (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 Beside the great sound characteristics, we treasure this pair because the pristine condition the two tubes are in - nearly 100% of the paint is intact, and the date codes etched on glass are perfectly visible - well nothing is easier to spot than date codes on Soviet tubes - simply look for the "74" letters on the glass and the Roman numbers before them stand for the months of production.

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.
