2 Vintage Matched
RCA/Tung-Sol
5881
Audio Tubes
NOS

 Buyer gets both of the tubes in the photos.  These tubes were tested in my Military Hickok Cardmatic & Maxi Matcher 2 tester to make sure these were great.  All the tests were excellent and both tubes test as new.  Both of these tubes were made in the USA, by Tung-Sol (branded RCA), in 1957.  These are the military, industrial grade, brown base version.

These are getting scarce and are a high end tube used by most of the professionals.   Great for any audio amplifier.  These tubes are what audiophile & guitar enthusiasts are looking for.  The tubes will come in the new RCA 5881 boxes, as shown.  These tubes are NOS (New Old Stock).  

*Please view all the photos carefully, as they are a big part of the description of all vintage tubes.  I will pack carefully & ship very quickly.
