 Buyer gets both of the tubes in the photos.  These tubes were tested in my Military Hickok Cardmatic to make sure these were great.   All the tests were excellent.  Both of these tubes were made in the USA, by RCA, in 1973.   These are the black round plate version.  
Great for any audio amplifier.  These tubes are what audiophile enthusiasts are looking for.  The tubes will come in their original RCA 6SL7GT boxes, as shown.  These tubes are NOS (New Old Stock).  I will pack carefully & ship very quickly.

*Please view all the photos carefully, as they are also a big part of the description of the tubes.
