6J3P  Vintage USSR Pentode Tubes 

                                                                           Lot of 10 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 factories and 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.
