NOS NEW 6J2P-EV 6Ж2П-ЕВ ~ 6AS6 5725 6F36 USSR audio pentode HiFi tube 

                                                                           Lot of 50 PCS.  
The valves in this lot are not tested prior to shipping. I will put a few extra valves free of charge as spares.
Valves may have been manufactured in different years. The valves may look different from the picture you see.  The picture shows random valves from my stock box.

Valve pins can be either shiny or gray.
The valves are more than 45 years old and the lettering on some cylinders has faded.

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.
