These tubes were tested in my Military Hickok Cardmatic to make sure these were perfect.   All the tests were excellent.  All 4 of these tubes were made in the U.S.A. by RCA.   They will significantly improve the performance of your amplifier.   These are the coin base, black plate version, with the side halo getter.
These are getting scarce and are a high end tube used by most of the professionals.   Great for any high end audio amplifier.  These tubes are what audiophile enthusiasts are looking for.  The tubes will come in the new brown boxes, as shown.  I will pack carefully & ship very quickly. 

Matching RCA codes the tubes: ET

Test results:  90/92, 90/92, 90/93 & 90/93, whereas a minimum good is 50 on this HIckok Cardmatic tester.  These are a matched quad, with super high test results.  A very rare find!
