+ 24 pcs X 6N23P (6Н23П) ~ E88CC ~ 6DJ8 USSR HI-FI TUBES vintage VALVES NEW

NEW 6N23P (6Н23П) tubes made in USSRVery similar to the E88CC, 6DJ8.24 tubes per lot . Tubes are not matched! Tubes produced in 1960-1970-1980sSome of the symbols on the glass bottles on some tubes are very pale and can only be seen in bright light. Tubes can be of different years of production. Some of the tubes have dark pins and signs of cleaning.ATTENTION:The 6n23p valve is only an approximate analogue of the ~ E88CC ~ 6DJ8 valve. Replacing one valve with another is not guaranteed to work 100% of the time. If you want to use 6n23p instead of ~ E88CC ~ 6DJ8 you will act at your own risk and the Seller is not responsible to you. Vintage valves 6n23p may not correspond to the datasheet parameters when tested at an anode voltage of 90-110 volts. The valves are tested with an anode voltage of 160 volts. 6n23p valves sound great and are suitable for many high-fi or high-end amplifier circuits. The valve manufacturer is Voskhod (rocket logo) or Reflector at my or your choice.Write me if you would like to have a particular manufacturer’s valve.Note: Voskhod and Reflector valves do not differ in construction or sound quality. Only your personal preference is possible here. IMPORTANT INFORMATION! BE SURE TO READ BEFORE ORDERING! In the title of the lot is the name of the vintage Soviet tube and after the symbol ~ the name of the Western analog. Be careful! Soviet tubes are only approximate analogs of Western tubes and match pinout, but are not exact copies of Western tubes. Testing Soviet tubes with Western-made tube testers can sometimes show unreliable results. Programs (Cards) designed for testing Western tubes can sometimes show unreliable results and erroneously show that the tube is not good enough. But these are unreliable results and should be disregarded. The volt-ampere characteristics of Soviet tubes are different from their Western analogs!Use for testing exclusively testers with programs for testing Soviet tubes. If you would like to get the datasheet for the Soviet tubes in this lot, please send me a message before you place your order and I will send you a JPG datasheet for the Soviet tube. Also, do not test vintage tubes with modern digital pulse powered tube testers. Use only testers with a classic power supply. For reliable measurement results, warm up each tube for at least 5 minutes prior to measurement. I do not accept any claims on the quality of tubes if you test purchased Soviet tubes of this lot on testers with programs (modes) of testing Western tubes or test tubes on digital testers with pulse power supply.TECHNICAL DATAFilament voltage, V 6.3 Filament current, A 0.29-0.35 Anode voltage, V 100 Anode current, A 0.01-0.02 Anode power, W 1.8 Steepness, mA/V 12.7 Reverse grid current, uA 0.2 Microphnic noise, mV 150 Gain 25.0-43.0 Dear customer, you can combine shipping buying more than one lot.If You need more than one lot, or another quantity – please contact.

Historic TubeMuseum, Tuxedo Park, New York Established in 1928 as a premier research facility in Tuxedo Park, New York, that attracted such brilliant and most visionary minds of the twentieth century – Albert Einstein, Werner Heisenberg, James Franck, Niels Bohr and Enrico Fermi to name a few. The Tuxedo Park lab attracted these top-flight scientists who experimented with audio, sound, time measurement, and radar (first klystron tube). Welcome to the …Visit this seller’s eBay Store!

HEERLEN HOLLAND FACTORYALL ARE PICTURES OF THE TUBE YOU WILL RECEIVE WITH THE DELTA Δ CODE GENUINE 1968 HEERLEN HOLLAND AMPEREX 6922 E88CC ALL TUBE MUSEUM TUBES ARE TESTED IN THE “FIXED-BIAS” MODE Most vintage tube testers test tubes by using fixed bias. So, if you are trying to compare test results between the AT1000 and other testers, this is the best way. The Tube Museum ALWAYS choose the “fixed bias mode” while testing our tubes. We only test in the “fixed-bias” circuit, this way drift or aging of the tube will not be compensated for, and your tube’s TRUE performance will be displayed on the LCD display, so you KNOW what you are REALLY buying! Here is the “6922” Amplitrex Set-Up Data Screen. The heater is a TRUE 6.3 volts, testing at the correct 90 eP with a mA Specification of the true factory data of 15.0mA and a GM or mutual-conductance (also known as mA/V) of 12.5mA/V or 12,500 Gm.There’s no fooling around at the Tube Museum with meaningless claims like “tests strong!”, or some arbitrary number like “the tube test 82 with a minimum of 75″ and no maximum stated! We always give you the test results FACTORY-DATA so you can compare with the real factory data sheets in mA and mA/V, just like the original factory data sheet! (specifications).
