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.
