Sovtek 6L6WGC Matched Pair / 5881/6L6WGC/6P3S-E

The 5881 is a Russian tube (6P3S-E) which was originally developed for use in military vehicles and aircraft. Here, exceptional robustness against vibration and mechanical stress is a core criterion. Today's commercial production which is mostly sold under the brand Sovtek / Russia corresponds in appearance and function to the military version. However, the original military goods are of consistently high quality and are subject to much less variation compared to today's purely commercial manufacturing. Therefore it is our endeavor to procure if possible this original military goods and prefer these qualitatively clearly before. Since the tube is technically, optically and in every application view identical, we reserve the right, depending on the possibility to supply the NN111 5881 as NOS Mil. Grade Version/ Sov. or from current production (Sovtek). However, the imprint deviates from the NOS military goods gü. the image what we ask to note!
